Balan Wonderworld? Yes, I love this game to bits. And the novel is so good too.

Alt text: Digital art illustration of Balan from Balan Wonderworld holding a yellow Tim. Balan is looking towards the viewer in a 3/4 angle view and is grinning as usual. He is visible up to the start of his legs. He wear white top hat with his eyes seen from the read band across the top hat, acting as a mask. He has dark skin and light green hair that looks like long balloons. He's holding the Tim, which is like a small yellow bird-like creature, with his right hand and his left hand is behind the Tim with his index finger pointing upwards.
