Toadball is like a mix of soccer (football for those outside the US and Canada) and volleyball. You have to kick the toadballs over the net and on to your opponent's side. You can either do a long kick with or a short lob with . Use the long kick when you are on the back third of the court and facing straight at the net. Use the lob when you are in the center of the court and facing the net. If the ball is in the front third of the net, simply bring it back and use one of the other kicks.
Occasionally a ball will start flashing, if it does this it is going to explode. If the ball is on your side of the net, quickly kick it over as you will lose points if it explodes on your side.
This achievement can only be done in Olympic Mode.
