The cow on the skateboard is called Kobe. She is Secret Agent Pi = 3.1416, and was the muse for De Moor and writer Stephen Desberg for a series of exuberant, mischievous, slightly anarchic comics. On the second fresco, Kobe is wondering where that enthusiastic mouse inside Tintin's rocket is travelling to. ‘When I read your books it's like a pot of paint being thrown in my face", an artist friend once told Johan De Moor.
