The bag with the mammuth exchange whoopiecushion fur is there. Don't mix them up.
I won't
You did, did you? Cletus is coming. Hide next to the pipe (click it).
How do I get out?
Did you read the ingredient warnings?
Of what?
Of the carpet cleaner.
Umm.. something something
Toothpaste. Combine it with toothpaste.
Chloroform...
Chloroform paste. Cletus has similar tube on his mirror stand. Look at the mirror, and screw the nut away with your screwdriver. Swap the pastes. Don't mix them!
How to get him to brush?
Throw a mothball into the pipe. He will eat one and start brushing.
But, switch-swap
You mixed them! Always the same thing.
What now?
Open the mirror. Maybe you could fool him. It opens a skippable minigame where you should follow his toothbrush movement.
Oppenbot!
Give him the money bag. Not the mammuth exchange relaycushion bag. Don't mix them!
I tried...
Of course. Go to the reception and talk with them. You get the plasma mammuth exchange thingy bag easily enough.
