Lego Adaptation Game/Fridge

Fridge Brilliance

 * Watching the opening cutscene of Lego Batman, This Troper wondered what a perfectly sane catburglar like Catwoman was doing in Arkham Asylum, as opposed to a regular prison. Upon completing her level in the game (at the end of which Batman captures her by putting out a saucer of milk and she just can't resist lapping it up like a cat), he understood: this version of Catwoman thinks she is actually a cat.
 * In Lego Harry Potter, why can the generic Death Eater pick up Mandrakes, who paralyse people with their screech? Because he's a DEAF eater!

Fridge Horror

 * The elephant you use to open the gate in "Pankot Secrets"... how is it supposed to get out?
 * Maybe it got off on the lower floor?
 * In Lego Batman one of the Joker's unlockable outfits is a tropical tourist's garb, with a purple fedora, Hawaiian shirt and a camera. It's a funky little ensemble, until you realise that it was what he was wearing when he shot, crippled, stripped and possibly raped Barbara Gordon.
