Froggy

Froggy (カエルくん Kaeru-kun) is a character that appears in the Sonic the Hedgehog series. He is the pet frog and best friend of Big the Cat, though he has a habit of running off on his own, leaving Big to set off each time to find him. 
== Personality ==
While unable to express himself vocally, Froggy has shown other ways to define himself: one of which is his rather bad habit of running off on his own, leaving his best friend to chase after him. When reunited with Big, the frog appears to be content with returning to his home at the Mystic Ruins.
Trivia
* Big has speculated that Froggy comes from Frog Forest, most likely due to his similarity with the local frogs.
* Froggy is one of only four minor characters to have his own toy, the others being a neutral Chao, Cheese and Kiki.
* Froggy has had both orange stripes and dark green stripes on his body. It seems he has green stripes in art and orange stripes in-game.
* In Sonic Adventure 2 and Sonic & Sega All-Stars Racing, Froggy is shown to still possess Chaos' tail.
* In LEGO Dimensions, Froggy appears as part of Big's quest in the Sonic the Hedgehog Adventure World, titled "Big's Big Fishing Adventure 4".

Froggy also makes a cameo in the Sonic Dimensions level, where he hops out of a portal during one of the cutscenes.
