There is a foe called Walruss that resembles a walrus is found only in a level on Gleam Glacier. He comes out and suprises Peach, but all you have to do is hit him multiple times with Perry. The Glossary entry says "Apparently spends time on the ice eating snow cones." There is also a calm Walruss in the background of Gleam Glacier, but it doesn't attack you and doesn't mention it in the glossary.
The Starfish is a very elusive and hard foe to beat. It is a reference to the game Starfy as the glossary says, "A star-shaped foe rumored to be the prince of a kingdom?" Starfy is in fact a prince of a kingdom. You can only find him in 2-5 in Hoo's Woods, 5-5 in Wavy Beach, and 6-4 in Gleam Glacier.
