On the wall are patches of bricks in the likeness of Mario, Mega Man, and another character that resembles the character from Pitfall.
The mining supply store has a picture of the Minecraft pickaxe.
Above the mining store is a poster of a tag team called "Los Super Hermanos", which looks like luchador versions of the brothers from Super Mario Bros.
At the top right corner of the map is a poster with "the hero" (luchador Link from The Legend Of Zelda).
On a missing poster on the far right of the level is the main character from Grim Fandango.
