The point of the Monkey Go Happy games is absolutely ridiculous. Yet somehow every time a new edition comes out (which is pretty often), I find myself playing it for way longer than I should.
The newest is the Monkey Go Happy: Dragon edition game (with a walkthrough here). It’s basically the same as all the other, you still have to cheer up a sad monkey. The only difference is that there is a dragon flying somewhere. Still, lots of fun though. Enjoy.
By the way, I never understood why it’s a monkey that’s sad. Most monkeys seem pretty happy to me!
