When he woke up, he found that only his brain was left in his body, and all other body parts were gone, replaced by four tentacles.
There is a mysterious stone staircase and a mysterious museum inside the brain.
He keeps eating all kinds of things to increase the number of tentacles. Eat the chip and grow a smart tentacle.
Eat a bug brain and grow a bug tentacle.
After eating the machine, a mechanical tentacle grows.
Eat books and grow a learning tentacle

Let yourself climb higher and higher on the stone ladder, and acquire more and more powerful skills.
The Mystery Museum collects all kinds of brains, those who are brave, scientists or have wonderful lives.
