I made list of remaining levels due to complete boredom:

Dungeon Dilemma
Knight Cap
Tossed Salad
Carrot Juice
Weirder Science
Loose Screws
Victorian Secret
Colonial Chaos
Purple Haze Maze
Funky Grooveathon
Beach Bunny Bingo
Marinated Rabbit
A Diamondus Forever
Fourteen Carrot
Electric Boogaloo
Voltage Village
Medieval Kineval
Hare Scare
Thriller Gorilla
Jungle Jump
A Cold Day In Heck
Rabbit Roast
Burnin' Biscuits
Bad Pitt

Voila. 22 levels left until end of episode, thus I assume there will be twenty two story posts or less.

Anyway, do you mean that Labrat levels were actually found by R.A.B.T.?
