How do you finish level 2 of plankton's fun house?

Everytime the tank shoots these black balls there's one which has a red/ orange arrow above it. You have to pick it up and bring it to the black thingys which have a blue arrow above, it doesn't matter which one just bring it to a black thing with a blue arrow above. Then that black thing will shoot the black ball at the tank. The tank will stand still for like 30 seconds. This is your chance to attack the tank. Now you can climb on to the tank. On the tank will be those red/ orange arrows again, this means you have to attack those things with the red/ orange arrows above. You can press y to attack it or maybe another one... just attack it...

If you run out of time the tank will throw you off of him. You have to do everything again, but everytime you have destroyed a thing of the tank it is still broken. Just continue with the black balls and attack it until you have destroyed everything. When it is beaten the game is cleared.

Ps. it doesn't matter which character you are: Patrick or SpongeBob

Is used SpongeBob.
