Well Philo and Gunge seem to have a bad memory as they have no idea where this home of theirs is, so they might easily forget Mcmooch, or she might have just observed his actions in Junior Sells the Farm.On the other hand, she states in the same episode that McMooch was an old enemy, which would appear to contradict this. So perhaps the truth is partially this and partially something else.
Yes, and in the episode "Don't Cry OVer Spilled Milk" Gobo distracts Sprocket by saying "Hey look Santa Claus" and in next season's "Manny's Land of Carpets" they don't know who Santa is and call him the wish-granting creature.I don't understand this plot thread at all and I don't even know how to argue it. There are a lot of continuity errors in the show I've noticed, namely in the songs.
Example: "Catch a Tail by the Tiger, Take the horns by the bull". But... but... how do they know what those animals are if they have never been in Outer Space?
