The Fairly OddParents S06E18 - Dread & Breakfast

When Timmy's dad, quits his job to become a sock monkey salesman (which fails horribly because no one wants to buy one because according to the episode "they don't do anything") the Turners turn their house into a bread and breakfast to avoid bankruptcy. Unfortunately, their first guests are Mr. Crocker, Dark Laser, and Tootie. Timmy cannot make any wishes, because if he does, Crocker's Magic Sensors will track the magic back to his fairies and capture them.
