name of childrens cartoon charater?

I was talking about this earlier with a friend, i used to love this programm and she said all the episodes are on utube.

I've tried googling it and putting it in the search on utube but i cant find it......because i cant spell it.

it sounds like u-la-seas.

Does anyone know how it is meant to be spelt??

Ulysses

your a star thanks!
