Super Mario Land 2: 6 Golden Coins
Game Boy Cameos

N&B Block

The final stage of Mario Zone is made of Lego-style building blocks. Around halfway through the level there is a split path, and along the lower path one of the blocks reads "N&B".

N&B Block was Nintendo's own Lego-style building block brand when they were a toy manufacturer in the 1960s and 1970s.

Gordo

Throughout the game are sea urchin enemies floating in the air that wiggle around as you approach. This enemy's sprite seems to be identical to the enemy Gordo from Kirby's Dream Land.
