The Seaweed Monster was an underwater Monster 

with Fins, Tentacles, and a Snout. 

The Seaweed Monster chased after Scrooge because 

Scrooge was afraid of the Seaweed Monster. 

The Music soothed the Seaweed Monster that 

Scrooge played the Harpsichord. 

This Seaweed Monster hangs onto a 

Seaweed under the Ocean. 

That Seaweed Monster was crawling on Land with his Fins. 

The Seaweed Monster snatched Scrooge's Hat with his Mouth 
that Captain Bounty saved Scrooge's Life.  

The Sun would scare the Seaweed Monster away 

and he went back to the Sea and hang onto the Seaweed again.
