The most challenging level of Dikembe Mutombo's 4½ Weeks to Save the World has just been released. Dikembe and Science the Bear are donning their most festive of holiday* sweaters, exchanging holiday* gifts, when they realize what they've been fighting all along — the INTERNET.

So Dikembe takes flight and embarks on a quest to annihilate any Internet meme in his path: from LOLCats to grumpy cat, and every dude wearing a horse head mask in between. Meanwhile, Science is launching a friendship attack from a separate location. They take quite a beating from the all-powerful Internet, and Science's life — and festive sweater — hang in the balance. Will he survive? Or simply become another Internet meme relegated to the goofing-off-at-work of yesteryear?

There are 2 days left on Earth (thanks, Mayans). Dikembe Mutombo needs your help in his quest to add more time to the calendar. Play Dikembe Mutombo's 4½ Weeks to Save the World here (or below!).

*Definitely not Christmas.
