Pikachu loves boxing. The fact that Pikachu is one foot tall hasn't stopped it before, it just starts swinging its fists. If it does this, let it tap you gently because if it gets mad, it will electrocute you.

If Pikachu starts to get angry, you might want to take counter measures�

And unless you are wearing rubber gloves, Pikachu will have the effect of being invincible as 10,000 volts of static cling go though its body.

Sometimes if Pikachu is being beat badly enough, it will rip-off a limb of a bystander and attempt to beat you with it.

If this situation arises, select any blunt object and charge Pikachu with it. Aim for the head and bash repeatedly until he drops the dismembered body part.
