|Normal gameplay||Bridge Building|
Similar to the last level, you need to push the Box three times, and every time you respawn, the Box goes back to its original place.
Use jumps to hit the Box, and land on the platforms. You need to memorize the route if you need this. Do a jump, then land on the platform on your left or right, then go to the Box, hit it, find a place to land. For the third hit, you just need to smack it, and even if you are about to fall it will send you to Level B-12.
Same as last one, this one is very easy as well. Use jumps to the platforms that lead to the Box (which stick close to the walls). It may be slightly harder than the last one since you need to push it for three times instead of twice, but given the fact that you don't need to start from the beginning and push the Box, this level is still pretty easy.
Don't forget that you need to push the Box to the next level. If the Box is still present in this level and you passed the boundary, you have to restart all over again.
