monster school cartoon... (CreepSchool (2004))

When I was little, maybe early 00's, I used to watch a about 4 kids going to a monster school. I've googled it like crazy without results. It is not Real Monsters or Monster High.

I think it was about four normal children, two girls and two boys, going to a school, for monsters. I remember one blonde kind of diva, called Victoria, the other was a semi-goth girl, one boy with an afro and wicked smart and the other being an asian kid with a rastafarian colored hat. The kids had their own bedroom in a tower with a huge circular window. The monsters were all very friendly but slightly weird and there were a lot of secrets in the castle-like school. In one episode there was a portal in a wardrobe I think and in another episode the monsters talk about how they invented halloween to be able to go in to the cities and party. And the vice principal was a gecko/charmelon/lizard in a suit usually.

This is about all I can remember. I can visualize some of the rooms but not enough to write down details. I hope someone out there can recognize this and name the show and maybe link me some picture/videos because I reeeeaaaaally want to know what the show was called.

I remember this. The principal was a frog. Sorry, right now that is all I`ve got.

I take it back. I`ve confused your description for MY GYM PARTNER`S A MONKEY.

Yes! That's it! Thank you! That's the one!
