The lab is dark; it is nighttime. The pudding cannon sits in shadow. Zoom, the mysterious sponge-like invention, is peering in.

It moves in front of the cannon and looks around cautiously...

...eventually settling down against the cannon to sleep.

Dobbsey walks in and notices Zoom. He looks concerned.

He pulls a blanket over the invention, being careful not to wake it.

Zoom sleeps contentedly.
