Gotta Catch 'Em All
Children love collecting things. It doesn't even really matter what it is; they just like seeing a few of something become a lot – a concept that can be found at the very heart of the Pokémon experience.

For Pokémaniacs who prefer a more tangible collection, there's a wealth of plushies, toys and duvet covers to collect in the real world too.
