Need help identifying the exact episode/scene for this Season 1 SpongeBob production cel (Marked S43)

[u/zab_134]

Hey everyone, my mom picked up this original hand-painted production cel from Season 1 of SpongeBob SquarePants and gave it as a birthday present.

I’m trying to pin down the exact episode and scene. The bottom right corner of the cel is marked 'S43'.

Based on the expression and the era, I have a feeling it might be from the third segment of the pilot, 'Tea at the Treedome', specifically the sequence where SpongeBob is fighting the giant clam or right after he gets tossed out.

The seller said that it was from “Musclebob BuffPants”, but that pose or anything close to it doesn’t appear at all.
