Who Framed Jimmy Neutron?/Flippy - S3-E14
Other mistake: Stormshuckle tells Jimmy he was able to get into his lab using DNA from Jimmy's spit that was left on a straw. Throughout the show, it is shown that Jimmy accesses his lab by scanning a strand of his hair, never his saliva.
Crouching Jimmy, Hidden Sheen - S3-E8
Other mistake: When Sheen is about to fight Yoo Yee, Jimmy puts the kung-fu disk in the dance machine. During the break in the fight, Jimmy asks Cark to get him the kung-fu disk to put in the dance machine, but Jimmy already had it in there at the start of the fight.
