Description by Ryutaro Nakano Written by the developer, not by AppBrain. Click to read.
Tap bloodworms to gulp them down! As regeneration energy builds, your axolotl's regeneration goes wild and morphs into all kinds of creepy-cute forms — a laid-back, slightly emotional idle collector.

■ How to play
- Just tap the food. Your axolotl chases and swallows it whole
- The more it eats, the more it regenerates into totally different forms
- 19 forms in total, plus rare & hidden evolutions and multiple endings
- Food piles up while you're away, so you always make progress

■ Features
- Easy one-tap idle raising
- Branching evolutions & hidden forms to complete your collection
- Fully playable offline (no account needed)
- Available in 10 languages

You'll keep wanting to see the next weird form. Discover the “truth” waiting at the very end with your own eyes.
