When your opponent is a long day filled with meetings and paperwork instead of a skilled Pokemon trainer, Pikachu, Charmander and Squirtle won't be much help. The real fighter you need in your corner is caffeine, delivered via this wonderful Game Boy-themed mug that's perpetually playing Pokemon.
Available from Esty seller TheMugEmporium for just $15.53 each, the mugs can be customised with one of five different screenshot designs, though they're all taken from Pokemon. But you'll want to act fast, because these clearly aren't an officially-licensed Nintendo product, and the creators have made no effort to come up with a clever alternate name. [Etsy via Geeky Merch]
