"*UPGRADED to Blue Whale!
Smash with your powerful tail!*"
The **Blue Whale** is a tier 14 Ocean animal in Mope.io, and the equivalent of the Elephant, Cassowary, Giant Spider, Mammoth and Blackwidow Spider. It was introduced on April 18, 2017.

## Technical

* Upgrades from the Killer Whale, Hippo, Boa Constrictor or Sabertooth Tiger at 650K XP.
* Upgrades to The Kraken, King Crab, Dragon, T-REX, The Bigfoot, The Yeti, The Snowman, or Pterodactyl at 1M XP.
* It can consume every food source in the game, except for dates, berries, and cactus pears.
* Predators of the Blue Whale are all animals within the range of tier 15 to tier 17 (Kraken to Black Dragon).
* Prey of the Blue Whale includes all animals between tiers 6 to 13 (Jellyfish to Killer Whale).
* The special ability of the Blue Whale is "Tail Slap". By pressing `W`, the Blue Whale's tail will slap the surface beneath it, damaging any animals in range and pushing them back. Afterwards comes a shockwave, which has a larger radius, but only stuns.
* The passive ability of the Blue Whale is "Exhale Food": whenever the Blue Whale dives, water pods, red mushrooms or plankton will appear.

## Appearance

The Blue Whale, unlike most of the animals in the game, does not have a circular shape. It has a rounded body, its face protruding at the front, and a large tail sticks out the back. The Blue Whale's head is rather narrow, and fins are short but straight Colored specifically in blue, its fins and tails are of a darker shade, and its sides have small highlights. Above its black rounded eyes is a black blow-hole that blows out water or other loot when diving.

With the exception of the Mermaid Whale, the Blue Whale's skins have similar physical features; the primary difference is their color.

## Strategy

### Using

* The Blue Whale is a powerful animal; its "Tail Slap" ability is useful for defending from predators and stunning prey. However, being larger than most other animals of its tier, the player will need to be careful of predators and small spaces.
* The "Tail Slap" will knock away and damage affected animals when used, similar to the Donkey's "Back Kick" ability. It requires great precision and accuracy, as the player will often need to swivel around and aim for prey from the back rather than a front-on attack. The shockwave and stun will aid in this but should not be relied on too heavily.
* Since a large amount of XP will be needed to level up to Apex tier, and the Ocean biome does not have food sources with high XP, farming prey will be the fastest way to level up. The "Tail Slap" ability will be the player's most effective tool for this.
	+ A good strategy is to dive and hide underneath hills and rocks, and use the "Tail Slap" on unsuspecting prey, especially if the animal has a damaged Health Bar.
		- When prey gets close enough, the player should use the special ability, and continue to bite/damage the prey while it is stunned from the shockwave.
		- Using the "Tail Slap" near beaches (edge of the Ocean where dry land is) will be an almost guaranteed win; by slapping prey out of water and on to dry land, they will be unable to dive or escape and the player can safely damage and eventually eat the prey from water. Be wary of any nearby predators such as King Crabs when doing this, as they could employ the same strategy on the player.
		- This strategy can be applied inversely to non-Oceanic animals too; any Land-, Arctic- or Desert-spawning animal that has wandered into the Ocean can be tail slapped further into the Ocean, making them potentially easy prey (some non-Oceanic animals have long diving time and will not be caught by this method though).
		- Predators may also become prey for the player; when there is a big fight going on between two or more apex tiers, when one of the animals has critically low health, the player can use the "Tail Slap" to damage and kill them. Being accurate in this situation is crucial as a miss could give another player the kill, or cause the player themselves to be killed.
	+ Alternatively, if the player has used the Blue Whale's special ability already, they can use the Blue Whale's larger size to its advantage by attacking prey when it is in a relatively enclosed area, or near an island (in the latter case, the player can push the prey on to the island and use the ability to keep it out of water).
	+ AI animals are also a good source of XP that are typically easier to eat than other players/prey. The "Tail Slap" ability can kill most AI animals – Frogs, Honey Bees, and namely Snails – in a single shot. Farming AI animals is a slightly slower way of leveling up, but will be more reliable if prey is scarce or if predators are abundant.
* As for predators, the main threats for a Blue Whale is The Kraken and the King Crab. Sea Monsters are also dangerous but are less common due to being high-tier. The Blue Whale's size as a result can work against it when facing predators which can constrain it between sandhills, so the player should utilize diving and whirlpool hiding holes.
	+ Since The Kraken's "Whirlpool" special ability can easily trap the player due to the Blue Whale's size, the player must always use their "Tail Slap" only when necessary as it can potentially save the player from the "Whirlpool" by knocking the Kraken back. This also applies for Sea Monsters.
	+ King Crabs are not as much of a threat since their "Arm Smash" ability will deal damage but pushes animals away from it. However, always avoid King Crabs near the beach/Ocean's edge since the "Arm Smash" could be used to force the player out of the Ocean.
	+ Other non-aquatic predators are not much of a concern since most of them are weaker in water, aside from the Dragon and Black Dragon (both have the flying passive ability). The T-REX, while slow, is dangerous as well since its "Bite Drag" ability can drag the player out of the ocean if used. For this reason, staying away from beaches with lots of predators is best.

### Against

* The Blue Whale can be a formidable opponent for predators and prey; its long dive time and defensive special ability both make it difficult to kill and hard to defend against.
* For prey (tiers 6 to 13): the best way to avoid the Blue Whale is to maintain high health so that it cannot kill the player with its ability, and to either dive/hide in a hiding spot or stick around sandhills.
	+ Trying to bite the Blue Whale's tail is risky since its special ability allows it to instantly respond with a damaging knockback effect. Tail bites are best done right after the Blue Whale has used its special ability.
	+ When being chased by the Blue Whale, if the player is unable to dive or hide in a whirlpool they should move close to the beach/Ocean's edge, as there is more chance that another predator might distract the Blue Whale by dragging/forcing it out of the Ocean.
* For predators (tiers 15 to 17): The element of surprise is key to killing a Blue Whale. Its ability allows it to repeatedly damage the player while knocking the player away, so acting passive until the Blue Whale becomes distracted with other animals will be more effective.
	+ The Kraken and Sea Monster are the best animals for killing a Blue Whale as their "Whirlpool" ability prevents the Blue Whale from escaping. This must be done ideally right after the Blue Whale uses the "Tail Slap" ability so that it will not knock the player away.
	+ As mentioned above, the player can also try to force a Blue Whale out of the Ocean due to its large size. The King Crab's and T-REX's respective special abilities will specialize in this.
	+ Hunting aside, if the player is a predator of the Blue Whale and has a low Health Bar, they must hide immediately as the Blue Whale can potentially kill the player through the attack-and-hide strategy mentioned above. Keep this in mind when doing 1v1 outside of the Arena in the Ocean.

## Trivia

* It is the one of the only animals with a unique oval-shaped design.

### Glitches

* When the Blue Whale's tail slap shockwave was added, it caused a physical effect on diving animals and animals that were using hiding holes/whirlpools; it could force the latter group out of the hole altogether.
