Mister has a Pokemon obsession.
(There's a reason Pikachu was one of MeiMei's earliest words.)
These books are great-- a simplified version of the guidebooks that tell older kids everything they could possibly want to know about each pokemon.
Big hit with Mister... and MeiMei... Boo prefers plain peeps. (That is exactly how she phrased it. Amusingly. Though not as funny as the day she said, in reference to her sister "She does monstrous deeds.")
