Cloning? Well, that's the key game mechanic. On each stage you can record a macro of P.B. performing an action. Using clones of yourself performing various actions is how you get all the pies before the time runs out. You might 'record' yourself swinging your umbrella. The clone will repeat this action ad infinitum. You can then run at your clone (or perhaps stand under it) and be launched by the umbrella towards the pies in the sky.
