He is just an unfunny stereotypical French jerk. As he betrays SpongeBob just because he wouldn't touch what he considers "filth" before running off.
SpongeBob literally sold everything he has (Including his own clothes) just to buy Le Spatula, only to get betrayed by him. Which is just a huge slap in the face.
He barely gets any more screentime in this episode at all.
He for some reason has legs, even though his purpose was to cook food and not compete in a running marathon.
He even goes as far as to punch SpongeBob, which makes him an utterly cruel and heartless jerk.
Speaking of WIS #1, he is kind of picky. The reason why he wouldn't let SpongeBob touch him is that he only prefers to cook fancy food rather than any other food, which makes the tool more worthless than it looks.
He never gets punished for his cruel actions towards SpongeBob.
Thankfully, he never appeared again after the episode, "All That Glitters".
Despite its poor execution, the concept of a futuristic spatula with a lot of features seems cool and creative.
It's pretty obvious that he was made to be loathed for being an entitled and snobbish piece of junk.
His name is not grammatically correct. Since in French, nouns have genders, the French word from "spatula" ("spatule"), the correct way would be "La Spatule."
