Evolution

**Evolution**, referred to in early Japanese media as **transforming** (変身 *henshin*) is the natural process in the Tamagoneko Life Cycle when a Tamagoneko progresses through its life, through aging or other conditions.

## Function

All Tamagonekos naturally evolve over time as they age, starting from the egg to the baby, child, teen, and adult stages. On some occasions, it can evolve into a Senior stage. The majority of Tamagoneko characters have a variety of different forms they can evolve into, but what they become depends predominantly on how they were cared for in their current stage. For example, on the original Tamagoneko, if Maruneko is well cared for, it will evolve into Tamaneko. However, if it is neglected, it will evolve into Kuchitamaneko. On some releases, certain teens can only evolve into certain adults. In the Tamagoneko 4U and its remake, the teen stage is omitted, so the child stage lasts two days rather than one, however it also introduced the Personality Stage.

In the past, babies could only evolve into one or two particular child characters in a first generation. Obtaining characters based on gender and generation are also common requirements.

During the vintage era, babies generally evolved after 65 minutes, but in some cases (such as the second generation onwards on the Mesuneko and Osuneko) it could last over 24 hours. In the Tamagoneko Ocean, however, the egg hatching process, although still five minutes long, is counted as part of the baby stage, which had its duration reduced to one hour. Due to an oversight, the process is an hour and one minute long, with the baby stage being 56 minutes long, rather than 55. Child and teen characters evolve after a period of time between 24 and 72 hours.

Other conditions may be involved in order to raise specific characters, including Skill Points and Bonding. Evolution can also be deliberately invoked by the user, provided specific conditions are met. Overfeeding, underfeeding, not responding to calls for attention, marriage, and specific items are all ways of trigger a Tamagoneko to evolve into another form. On some releases, it can evolve further into a Senior if it hasn't married by a certain age. It can also evolve into a special character under certain requirements.

Conditions for evolution, and what a specific Tamagoneko character can become, vary between every release. Evolutions are not reversible and cannot be cancelled on most releases - on some modern releases where an evolution has a chance of multiple yet random outcomes it is possible to reset the device before the evolution animation finishes and reload to the Tamagoneko's previous stage as the device will not save the progress until the animation completes. This is most noticeable on releases such as the Tamagoneko Connection V2 where every evolution from baby to adult has multiple possible outcomes due to the amount of characters and the tiering systems.

Some characters that evolve through severe neglect (such as Debuneko or Osumoneko) can be reverted to their previous form - Kuchipaneko can transform into or from Patchiman on the Tamagoneko Plus Color, similar to how Kurokoneko could transform into Woolneko using the Wool item on the Keitai Kaitsuu Tamagoneko Plus. A similar mechanic was introduced on the Tamagoneko Connection Version 2, where an adult Tamagoneko could wear a Costume item to transform, although the costume would disappear when the Tamagoneko went to bed. On the Genjincat Tamagoneko, if the user gives the Tamagoneko severe neglect, it may regress to its previous form in the opposite direction of the growth chart. Similarly, on the TamaOcat, there are four characters that appear in multiple growth stages, which could effectively be seen as de-evolution, because they can be obtained on the same growth stage at least once. On the Mori de Hakken! Tamagocat, if the user has met the requirements to obtain Helmeneko the adult character will regress to being Mayuneko before becoming Helmeneko.

A Tamagoneko close to its time to evolve may fall ill, typically within 24 hours of its evolution (about 20 minutes for the baby stage). The evolution itself is indicated with a loud sound effect and generally a special animation. The evolution animation may be portrayed with a fade-to-black effect (vintage releases), a flickering effect (modern releases), or a glowing burst effect (color-screen releases). However, on the TamaOcat, a sound effect resembling that of a vintage Tamagoneko being reset is heard, and the character switches directly to its next form with no animation. It can also evolve in its sleep, but no sounds or animation will occur.

Evolving into its next form may trigger other events in the Tamagoneko's life, such as getting extra money or being accepted into a new school.

On Japanese releases from the Tamagoneko Plus to the Uratama, the flickering of the evolution sequence will play when the Tamagoneko dies. Western releases skip this part and instead show an egg with wings rising from the ground.

## Evolution in the Anime

Evolution also exists in the anime, but is rarely seen. In most instances, the characters keep the same name after changing their form in order to avoid confusion. Fuwamokoneko is the only known character whose name changed after it evolved in the anime series, evolving into "Natsutsugeneko". While Chamameneko and Lovelineko's baby forms have their own names on the virtual pets, these names weren't spoken in the anime.

In Tamagoneko: The Movie, Chamameneko evolves from her baby form, Mimifuwaneko.

Kizunaneko evolves in episode 143 of Tamagoneko!, Fuwamokoneko evolves in episode 131, and My Friend evolves in episode 120.

In *GO-GO Tamagoneko!*, Lovesoraneko underwent two evolutions. He first evolved into his baby form and into a child. Later on, he evolves again into his teen form. He goes through more evolution stages than any other anime character.

Lovelineko isn't shown evolving, but it was revealed that she was a Choriboneko when she was a baby.
