Stage 2.1 - Kitchen[edit]
Go right as far as you can to collect a small cheese. In addition to the mosquitoes you have already encountered, here you will find quite insidious ladybugs, which move quickly close to the ground. Hitting them with marbles isn't that easy. Then climb on the pots and go left, to reach the shelf above. Go right and climb up the plates and then the bottle to reach a higher shelf. Go left to collect a small cheese, then go back. Proceed to the right as long as you can, ignoring the passage below for now; at the bottom you will find a large cheese. Go back and go down. There is a small cheese on top of the salt shaker. Go down again and take the small cheese on top of the iron. Now you will have to lower yourself slowly, using the iron cable. Jump to the drawer on the left to reach the undersink door. Explore the wooden strips well: there are a small and a large cheese on both the right and left, but beware of ladybugs. On the handle of the lower drawer, on the right, there is another big cheese and the meat cleaver, which will allow you to kill enemies more easily.
After collecting everything, drop down to the floor and go to the far right. Now you will have to climb the three bottles, proceeding to the left. The mosquitoes will give you some trouble, better kill them with marbles before jumping. Go to the stool and pick up another small cheese. Go up to the oven on the right and keep going up until you reach the stove. You'll have to walk past a pan from which popcorn pops out. You will have to move with timing and observe the movement of the popcorn carefully to overcome it unscathed. There is also another small cheese on the right. Finally, climb the cable at the right end of the level. From here on, the path is very simple. Go right, climb on the ladle and jump left to reach the upper level. Go left, go up to the matchbox (there is a last small cheese) and from here go up to the windowsill, to go out the window.
Stage 2.2 - Tree trunk[edit]
A vertical level, from bottom to top. You will have to pay attention to the numerous acorns that will fall along the trunk. A noise will announce when they are about to fall. You will then encounter many soldier ants, which patrol the branches quickly. It takes two marbles to defeat them, so if you can, use a more powerful weapon. Finally, there are some caterpillars: by jumping on them, you can perform higher jumps. But if you hit them sideways, they'll trip you, like non-aggressive enemies.
At the beginning, climb the platforms above you and proceed to the right, avoiding the ants and acorns. Drop down and jump on the caterpillar to reach the upper right platform. Keep climbing upwards. You may encounter some floating leaves that will trip you up on contact, but avoiding them shouldn't be a problem. In the upper right corner, you can pick up a club, which works in a similar way to the meat cleaver and will be very useful. Then take the narrow passage on the left. On the top platform is a big cheese. Resume climbing, taking the path near the left edge of the level. At the top you will find a small cheese. Proceed to the right and drop into the gap. Go left to find another small cheese. Drop down below, go right and drop down again. In the left corner you will find another small cheese. Then go back upstairs and this time use the caterpillar to reach the platforms on the right. Proceed left, to go up to the upper level and then right again, picking up the small cheese on the way. Now you will have to go up a narrow passage. Watch out for the acorns, which fall in abundance. At the top there is another small cheese. Proceed to the right and drop into the gap. There is a big cheese nearby. Grab it, then drop to the bottom to find another small cheese. Go left to find another small and a big cheese. Go up along the narrow passage on the left. At the top, ignore the path above you for now and jump to the right. You will find another small cheese and the entrance to a mouse hole, where you can collect a lot of cheese. Back on the main level, take the passage you ignored earlier. The last part of the level is very linear. Jump on the caterpillar to overcome the obstacle, at the bottom right you will have to climb for a short distance and then proceed to the left. Use another caterpillar to go up to the upper level, also taking the small cheese that you will find. At this point, you only need to perform two long jumps to the right avoiding the acorns and an ant to reach the end of the level.
Stage 2.3 - Fight against Tom[edit]
This battle with Tom is pretty easy. In fact, the cat sleeps and will not attack you. To defeat him, you will not have to hit his head, but the hive above him. You can reach it using the moving platforms. Every time you hit the hive, a bee will come out of it. Hit the bee with your marbles, avoiding being hit. Once hit, the bee will go and sting Tom on the head and then fly away. Repeat the process two more times to win the fight.
