Sergei and the Pipe

This is when the Pipe sucked Sergei from his Inner Tube that

floats on the Water after he was sucked into his own Nightmare  

by taking a Nap in "Swan Meat".

There was a bulging Part of the Pipe and it was Sergei being sucked in  

and also there were Trees, Plants and Mushrooms when Sergei was in the Pipe  

goes into the Building. 

The Pipe popped out Sergei and he sat on a Chair in the Psychedelic Room 

while Sergei has a friendly toothy Grin on his Face.
