he was Juandissimo Magnifico from the fairly oddparents and rocko from rockos modern life . !
My guess is that Joe Murray (The creator of Rocko's Modern Life) needed a 7 year break and started working on Camp Lazlo.Also,maybe it was because Nickelodean wanted to make VHS's and and DVD's and it took them a lot of time working on it.
ok there is an old tv show called rockos modern life about a kangaroo who comes to America or whatever he has these little animal sidekicks, Wikipedia it, anyway apparently he's a demon who made his master angry so the things he goes through in the tv show are his punishment, phineas and fern are said to be the sequel of thiis
