Tom & Jerry: The Ultimate Game of Cat and Mouse/World 3

Stage 3.1 - Roof
You will now find yourself on the roof of the house. Along the way you will encounter many floating leaves, which can make you trip. Go right, defeating the squirrel and enter the long gap you will encounter. From here, go all the way to the left jumping over the purple gap to find a small cheese. Then go down into the gap and take the big cheese. At the far right you will find another small cheese. Go down again, you will find a small cheese on the left. Keep going down. On the right there are two big cheeses and one small, while on the left there is another large cheese. Just watch out for squirrels throwing acorns. Stay left, climb as far as you can and proceed left to find another small cheese. Then let yourself fall to the bottom.

Now go right as long as you can. Use the nail to go up, overcoming the obstacle and drop again to the right. Keep going until you reach the right edge of the level. From here, start climbing, also taking advantage of the bricks on the right. Watch out for squirrels. On the third axis there is a small cheese, on the left, while another is on the fourth, on the right. Here you will then notice a passage in the wall on the right. This is the entrance to a mouse hole, enter it and collect the cheese. Go back and go left as far as you can, past the gap. Use the nail to go up to the upper level and go to the far right. You will have to overcome three gaps, one after the other. Go up two levels and proceed to the left, crossing two more gaps. At the end you will find a nail, which will allow you to return to the top of the roof. Now go to the bottom right passing the two gaps you will encounter. There are also two small cheeses in the middle. Defeat one last squirrel and enter the chimney to complete the level.

Note: there is a trick to pass this level in a very short time, but you still need to have a bubble gum. At first, instead of entering the large gap, you can use a bubble gum to overcome it. Once on the other side, you can proceed directly to the finish line. It is possible to perform this move even without bubble gum, using a floating leaf that can push you to the other side while you are in the air, but it is extremely difficult to perform.
