While the Galidor PC/console game... isn't exactly known for being a gem, (even with its own lead designer dissing it), its GBA cousin isn't as botched from what I remember of playing it at a friend's house. The GBA version is a sidescrolling platformer, nothing special, but not bad.
Anyway, it has a LEGO test level, apparently. Mildly interesting given that the franchise usually stuck to its own... style?... rather than going LEGO-y.

Tangentially related - Super Mario Land 2 has a level made out of totally-not-LEGO blocks.
Apparently they're N&B Blocks, a clone Nintendo themselves made back in the late 60s/early 70s: http://nintendo.wikia.com/wiki/N%26B_Block
