Clowns are supposed to be humourous, but Zombozo gave me the heebie-jeebies the moment I saw him. Not a whiff of clown-comedy at all, I would say. However, for some unknown reason he manages to make the audience laugh, and steal their happiness to power himself up, claiming that is what all clowns want to do. That sounds weird since this is the first time I have ever heard of a clown extorting merriment in such a way.
Apart from the oddness of the situation, the graphics were also vividly enticing, giving us a feeling that Ben is trapped in Zombozo's maze of illusions.
