I haven't seen those for probably 25 years and I do remember looking forward to and enjoying them on Saturday morning. However, this is all I remember from the cartoons:
Larry says, "Oh, oh! It's 0-0-0!" Then a projector pops out of one of them.
The letters M, L and C collapsed on one another to segue between scenes.
One day I may get the opportunity to revisit these. Odds are I'd hate 'em, but I dunno... I'm one of those weird sorta ducks who likes the DeRita pictures. Ergo, I may actually like 'em!
