Magic Crayon - Wizards GUAL?

[gaduff]

While playing a game of Munchkin Legends with my brother and father, my father (a wizard at the time) played the Magic Crayon card. He followed what the card said (pick up three cards, or whatever), AND he went up a level. I asked him why, and he showed me the card. The card text says nothing of the sort, but the IMAGE shows a wizard writing on a wall with (presumably) the magic crayon. The phrase he is writing says that wizards go up a level. Is this part of the rule, or just part of the illustration? Do wizards GUAL, or don't they?

Furthermore, it also says in the illustration on the wall that warriors suck and get rocks thrown at them. Do Warriors then get "rocks thrown at them?" If so, what does THAT mean?

It's just an illustration. The rule is what is printed in regular type on the card.
