Role in episode[]
When Squidward escapes from the cabin and the campers cannot find where he is, Sandy pulls out her Stink-O-Meter and puts it on her nose. She smells SpongeBob, causing the Stink-O-Meter to flash green and say "P.U." She notices an absence of stink, indicated by the Stink-O-Meter flashing blue, which leads her to the outhouse. She smells a trail of stink from inside of it, and assumes that Squidward is not there, leading her group past the outhouse. However, Squidward turns out to be clinging to the top of its inside. He runs off into the other direction, and Sandy chases after him, with the Stink-O-Meter still equipped. However, when she falls into the lake, it comes off and disappears.
