I have been trying to identify an animated TV show of which I saw a couple episodes as a kid, probably around 2010. It was likely a parody (or at least comedy) of the superhero genre. The main character was superhero or special agent kind of character. I think he had a number of gadgets, but don't remember exactly which. At some point he may have used something like a stink bomb. I am not sure whether he also had any supernatural special powers.
In one of the episodes, there was a humanoid snail character, that I think was the main antagonist of the episode. He was human-sized and had a human face (like older? man), but his body was build like a big land snail (although I think he had hands) and he had a shell on his back. I am not sure why the MC was after him, perhaps he suspected him of something, or was trying to thwart some evil scheme?
There was a rather hilarious "stealthy" pursuit scene, where the main character was driving his car and tailing the snail across the city, but the snail was moving at a typical snail's pace, so the MC had to match his speed. I also think the MC wasn't very subtle, driving his car only few meters behind the snail (perhaps as a parody of such scenes in police procedural shows).
In another scene, the humanoid snail was eating in a posh (French?) restaurant and he ate some food made from snails (e.g. something like this WARNING: gross image of French cuisine linked, do not view while eating). Eventually, the MC followed him to the restaurant and they talked. Then there might have been a fight scene against the antagonist's henchmen. I don't remember much of the rest of the episode. There might have been a twist in the end, like the MC falsely suspecting the snail of crime, or being forced to work with him, but I may be mixing things up with some other show.
I think it was a parody/comedy based on the above. And I also have a feeling there was something funny/lame about the main character, like he had some lame power or silly superhero name. It was set in a contemporary city and I think most of the characters were humans (i.e. humanoid characters like the snail were not common).
I tried to write everything I could remember, but my memory of it is very hazy and it is likely I misremembered some details, so don't get discouraged if you have at least a partial match. The snail pursuit scene is what I am most confident about.
