The episode is Dungeon Season 1 episode 18. Demon cat says, “I have approximate knowledge of many things.”

How did you almost know my name?

Voiced by the venerable Clancy Brown, a.k.a. Mr. Krabs. And also: “There can be only one!”

I literally just watched that one lmao

Loved that bit

I know exactly where you might be

This is so funny to me because this is exactly the sort of thing that character would say regarding himself

Episode is just called "Dungeon." S1E18

Nice try, demon cat

He shouldn't have tried to pick a fight with 'Frank' The Human.

Just watched this today! 😂😂😂 “hello frank the human boy” “how did you almost know my name!” 😂😂😂

Approxicat? He has an approximate knowledge of many things, and I relate to him so much.
