Aqua Unit Patrol Squad 1

The knife on Happy Time Harry's arm constantly switches from being on his right to his left hand.

Err says that the Trees are catching a ride with Flargon and Dingle,but when the Wooden Ship is shown Merle is shown with Flargon instead of Dingle.

If you look closely when Frylock shoots the lightning bolt from his eyes, you see that it hits Happy Time Harry.

In this episode the cube doesn't die and yet ends up in hell somehow.

Major Shake is ran over by a truck in this episode and still survives.

The keg bucket is actually Carl's pool reshaped and painted green.

If Emory and Oglethorpe weren't invited because they were teh suck, as Ignignokt put it, why was Major Shake invited? He was a creation of the Plutonians. (Edit: If you hadn't noticed, Major Shake was a bit more intelligent, if not more popular than Emory and Oglethorpe)

What happened to Bingo the Robotic Floating Clown Head? Editor's Note: It is very likely that they skipped over reusing this character, since it never really played a valuable role, even in the episode it originally appeared in.

How was D.P. at the convention? If you remember, he was killed after being shot by the lasers on Carl's defense system. Also, why would he be there because he was never an enemy? He hung out with and sort of became friends with the Aqua Teens. (Edit: A couple of the villains there weren't actual 'enemies' such as Oog or the Cubes more annoyances in the AQHF's lives. Note Ol' Drippy was there though he was supposedly killed as well)

Right after Romulox eats the sundried tomatoes and vanishes, Oog says "He disappeared" without his mouth moving at all.

After the Quad-Glacier has been fired, we see the orange square for a long time. If you watch closely, it doesn't move very far. In fact at one point, it stops all together.

How does the wig from "The Clowning" freeze people? First it was Steve, then Randy the Astonishing. Yet, Carl is frozen because of Frylock... so how and why are the others being frozen?

In this episode, Err asks who Zarnold is but DP is the one who answers and says "Dude! They call me Skeeter, dude!" Why would he answer for him?

Why was Ol' Drippy there? He wasn't necessarily a villain. If I remember from "Ol'Drippy", he saved Shake's life and got everyone coffee.
