Plot hole: In the episode "Where's the Wizard?", when Pim gets the Wizard from Lil' Danny, she holds it in her hand. When Lil' Danny steals it, he takes it out of Pim's backpack, meaning it must be Pim's Wizard. But when Phil points it out, she says it's hers. This could be a character mistake, but if it was Phil's Wizard, they would not be able to track the one Hackett had, because inputting the signal of Phil's Wizard would do nothing.
Plot hole: In the episode where Phil is zapped by the New-Ager making him act young, at one point, he zaps Keely with the New-Ager several times, and yet, she isn't affected at all.
