If you know someone looking to enhance their game first thing in the morning, this Super Mario heat changing mug might just do the trick. It's ideal for NES and Mario lovers, but Mario has become a key figure in pop culture in general, so it works just as well for even non-gamers.
When cold, the mug depicts a level scene with the black background that looks like it's straight out of world 3. Add hot liquid, though, and the scene explodes with detail. Along with the background turning blue, smaller things like coins, enemies, and clouds appear, in addition to an invincibility star. Pour coffee, get invincibility star. Coincidence? Definitely not.
