Giant Squids are gigantic squids that are sometimes seen in the game Aqua Grabber. It's unknown what color they are, as it is too dark where they live to see. It appears in Clam Waters (Stage 1), but only sometimes. Before you see the squid, the screen will shake. It also appears in Puffle Rescue as a giant shadow which you have to follow in order to get the Moss Key Pin. They also appeared at the Iceberg during the Island Adventure Party 2010.
Squidzoid is fictional enormous penguin/squid combination that is large enough to devour buildings, as seen when he eats the Pet Shop. After being hit with the fused powers of Shadow Guy and Gamma Gal, Squidzoid was transformed into his previous state of a normal penguin. A Squidzoid costume was available for Members to purchase from the Costume Trunk.
