8 - 17: When L.O.S.E.R.S. Attack

Timmy Turner's enemies collaborate to form the League of Super Evil Revenge Seekers (L.O.S.E.R.S.) in order to annihilate him at the same time. When a rare astronomical event known as the Fairy-clipse does not allow Cosmo, Wanda, Poof (and also Foop) to use their magic to save him, Timmy is capable of outwitting the L.O.S.E.R.S. by himself.
