Just sharing episode ideas, you guys should to in the comments.
A Tweek and Craig episode where Craig starts to be frantic due to Tweek's influence.
A Randy episode where they experiment with more kinds of drugs on Tegridy Farms (cause it worked pretty well with Christmas Snow).
A Proper Clyde episode (cause Clyde's 4 episodes aren't entirely Clyde episodes), it could be similar to the Pandemic episodes, where the boys let Craig (or in this case, Clyde) into their circle.
An episode where Kenny finally takes his hood off and talks the whole time.
A Freaky Friday style episode where Butters and his dad swap places and Butters gets to show his dad what grounding him really feels like.
An episode where Scott Malkinson tries to find a cure for diabetes (which could be funny).
Kyle and Heidi episode, a way to reintroduce the Heidi plot in a really satisfying way.
An episode where Kyle gets Cartman expelled by exploiting PC Principle's PC Culture and listing all the things Cartman has done wrong.
A Stan and Cartman episode (cause from what i've seen, they've never had one).
An episode where Jimmy finally understands that Nathan has it out for him, and tries to get him back.
The Whites and the Blacks (as hinted at in "Basic Cable")
