[CATO Butter Cat Clearance Guide]
[Chapter 1 - Level 4]
1. First we come to level 4, go to the left to the gap in the acid, and separate the toast from the cat.
2. Then after we come down, the cat goes directly to the right through the wall. Operate the toast to go over the wall to the right and merge with the cat.
3. We need to separate again at this position. First let the cat climb to the top on the right, operate the toast to jump left and right in the upper gap to join the cat on the right.
4. Let Toast jump up here to enter the hidden room. Pay attention to the position of the cat's paws and the gray blocks below.
5. We jump directly up and click to separate. If the position is correct, the toast can be attached to the left wall.
6. We let the cat enter the pipe on the right and control the toast and the cat to climb up at the same time. The toast does not need to be clicked back and forth in one direction.
7. We come to the top. After combining, go to the upper hidden passage on the left to reach the hidden map, where you can get the achievement - [How did you get in??!].
8. Finally, we return to the original position, collect all the blue substances, separate them to the left, and then rejoin them to enter the portal.
