Tim and Xandir, Sitting in a Tree... - S2-E11
Continuity mistake: When an Entertainment Weekly magazine falls onto the table and Foxxy and Clara both hold it. If you look at Foxxy's hand you see that her furry bracelets suddenly disappear and then reappear.
Captain Girl - S2-E9
Continuity mistake: When Wooldoor hijacks the car, the rear window doesn't have anything on it. When Wooldoor gets in the car and drives away, a "Baby on Board" is seen attached to the window. (00:12:30)
Captain Hero's Marriage Pact - S2-E4
Continuity mistake: While pretending to be Waldor, Captain Hero approaches Unusually Flexible Girl, who is wearing a wedding dress which is cut very low at the back. All of the tattoos we saw earlier have disappeared.
Other mistake: When Toot is in the attic and discovers The Legend of Xandir cheat book, the first code she uses is up, up, down, down, left, right, left, right, B, A, start. The only problem is the controller attached to the book is a Playstation controller. The Playstation controller doesn't have an A or B button but an X, Triangle, Circle, and Square button.
Requiem for a Reality Show - S1-E4
Continuity mistake: When Toot enters the rec room to show Foxxy and Xandir her new slim body from constant vomiting, the rec room is completely clean. After she leaves, the room is now covered in vomit.
Answer: She was in the show 90210, so I'm guessing it's a reference to something she did in the show?
