Tom & Jerry: The Ultimate Game of Cat and Mouse/Mouse Holes

The mouse holes are hidden areas within the levels, where you can collect a lot of cheese. There are five in all and they are found in the levels below.

Level 1-1 This is very easy to find. Immediately after the first glass you encounter, jump to the top left. After a few steps you will arrive at the entrance. Inside, you will find many small cheeses. To return to the main level, exit the way you entered.

Level 1-2 This secret area is well hidden. At a certain point in the level, on the right, there is a ladder with three rungs, which you will be forced to climb. Soon after, you will notice a pipe above you that is normally unreachable. To reach this mouse hole you will in fact be forced to use a bubble gum. Furthermore, in this secret area you can also die, because the lower part is completely flooded. You decide whether to enter or ignore it. To return to the main level you will have to reach the left end and climb the pipes.

Level 2-2 A little before the end of the level, from the third lighter wooden platform, go up to the right paying attention to the acorns and enter the hole that you will find. You will find many small cheeses and two big cheeses on this branch. However, there are also some enemies in this secret area. To return to the level, exit at the top left.

Level 3-1 Once you reach the right end of the level, go up against the brick wall. You will notice a passage on the right. Enter it and you can get a lot of small cheeses and two big cheeses. Very easy to find.

Level 4.1 This is undoubtedly the best hidden bonus area. Shortly after the start of the level, climb on the NES controller. From here, making a slight jump to the right, you can jump on the buttons of the video recorder. To reach the bonus area, you will need to enter the videotape compartment. In addition to many small cheeses, you will find three big cheeses.
