Use your imagination...
"SpongeBob and Squidward accidentally let Plankton slip away with the formula, and it's up to them to retrieve it"
I think I can recall this episode being called Bottle Burgers, for some reason. Anyway, hasn't this plot been done before? I mean Plankton got the formula in F.U.N, and SpongeBob went after him to get it back. This feels like that, but a full episode and Squidward along for the ride.
This episode comes out on 13th April 2018
