About
What you eat becomes a momokoo inside your gut.
Merge matching momokoos to grow them, and expel them once they reach level 4.
■ How to play
· Food entering the gut hatches a momokoo of the matching type
· Momokoos of the same type and level merge when they touch
· A level 4 momokoo is expelled, giving back points and space
· If you run out of time, the momokoo drops right where it is
· When the danger line fills up, the run is over
■ Six momokoos, six expel effects
· Happy Gold (balanced meal) — expels every level 1
· Spicy Red (hot pepper) — blasts out the level 1s touching it
· Sick White (cold food) — expels level 1s in the same column
· Blunt Black (dry snack) — expels level 1s stuck at the bottom
· Hungry Brown (greasy food) — turns nearby level 1s into Brown
· Strange Green (stress) — adds extra time for a while
The food decides which momokoo is born.
Check what's coming next, then choose what goes where.

What's New in MOMOKOO MERGE
1.0.5
September 16, 2026
· The leaderboard used to stop at the top 50. It now shows everyone, so you can scroll all the way down and find your own rank. The ranking rules and the MY RANK panel are unchanged. · The background music file is smaller, so the app is lighter. It sounds the same.
