The Krusty Krab 2
The Krusty Krab 2 is the second restaurant founded by Eugene H. Krabs. SpongeBob SquarePants is the manager. It is almost identical to the Krusty Krab. It appears in The SpongeBob SquarePants Movie. In As Seen on TV a second Krusty Krab appeared but wasn't the Krusty Krab 2, since it was just a commercial prop and didn't have a 2 on it. SpongeBoob O's is The Second apperance. The movie comes after all the episodes so the Krusty Krab 2 is not seen again.
It also appears in "As Seen on TV (Episode)", but it is only a prop.
