My theory is that Psychic type pokemon are really possessive: Spoink cherishes it's ball, Slowking and it's crown, Mewtwo and his clone army. Even the move "Trick", psychic pokemon only developed for their own greedy intentions. They aren't very nice when it comes to items... so I say when Abra evolves it develops kleptomaniac symptoms. Wild Kadabra steal spoons from towns and break them when they get bored (If they are owned by a trainer, they steal them from the trainer). Then they make people forget that they ever had spoons. Alakazams are even better, they steal two spoons and brag about it to the other Kadabras and Abras in which they get jealous and train to get stronger such that one day they can steal two spoons as well. They should learn to share like pokemon like Aipom, Cubone, and Chansey. Pokemon who happily share their items with others.

So the moral of the story? All magicians are thieves.
