The second thing is in there science class they have this teacher. The teacher’s name is Mr. Sparks. This year Leon and his friends class are learning about potato chips! Leon already has a very good experience with chips so he decided to join a potato chip contest. The 3 people in the chip contest were Mr. Furtels. Mr Furtels is a scientist that studies chips. Another person is Alphonse Cipollini. Alphonse had won 5 contests in a row so that made Leon very nervous. The last person was obviouslyLeon. The reason why Leon joined the contest was because he needed to buy this army jacket so he could trade it with Lumkin. In the trade Leon’s army jacket would be traded for Lumpkin’s army jacket. Leon is doing this trade because in order to finish the voo-doo doll he needs something from Lumkin to stuff in side the doll for stuffing. The winner of the chip contest would get 800 dollars and Leon did not have the money to buy the army jacket himself. If you want to figure out if Leon wins the chip contest or if he ends up getting the jacket and getting revenge on Lumpkin read Leon and the Champion Chip.
