Help Identifying Gadget Boy cel

Hello. Relatively new to cel collecting. I was wondering if anyone could help me identify this cel from Gadget Boy.

The writing on the bottom of the cel is #105-286, so I assumed it was from episode 5. However, several sources list episode 5 as being a different episode depending on what episode guide you go off of. Wikpedia lists episode five as "Gadget Boy and the Wee Folk," and other sources seem to confirm this. However, sources such as TV.com contradict this by saying episode five is actually "All That Gadgets Is Not Glitter." Can anyone help me out?
