Dr. Rhymenstein

Dr. Rhymenstein was a scientist that was the father of Clementine and creator of the Purple Orange, in the dream of Binky Barnes.

He is a brown rat like Nigel Ratburn, however, unlike Mr. Ratburn, he speaks in rhyme just like all citizens of Verseburg. He lives in a mansion.

Trivia

 * His name could be a parody of Dr. Frankenstein.
 * He's a rat but his daughter is an aardvark, suggesting Clementine could be adopted.
