@Star: As someone who also has fondness for animals of the plush variety, your penguins are adorable!
Those are the Waddles brothers! My main men. Waddles and Megawaddles. Pretty much the heart of my collection and basically my "babies", in a non-creepy not taking them outside in a pram sort of way, but will still probably go into a burning building to save them sort of way. They have extended Waddle's family that has been acquired over the years, every Waddle's is a penguin but not every penguin is a waddles.
For instance there is Japanese Waddles, Christmas Waddles, Jumbo Waddles, Micro Waddles, Tiny Waddles, Mini Waddles, Spooky Waddles and Paddles (the only girl Waddles). The penguins that are not Waddles' include Icicle, Fairbanks, Gladis, Chilly, J'acuse and Mini J'acuse. That's all the penguins, but I also have a lot of ducks as well.
Now, I also collect rubber ducks, which I have around 40-50 of, but those don't get named. The named plushie ducks include Artemis Van Der Beak, Shoeburt, Impersaduck, Duckcast, Barbara, Mother Duck, Transport Duck and Huck.
Other species include:
Snails: Mayor Brian Snailton III and his cousin Titania
Bees: Sting, Rumble, Bumble, Brumble, Thimble and Wannabee (Who is actually a lemur dressed as a bee)
Seals: Sealia, Dealia and Amealia.
Elephants: Eliot (the Boxaphant) his sister Juliet and his girlfriend Cuddlz
Geese: Wanda and Ripple
Lemur: Sherlock and Repose
Platypus: Snooty and Scrooge
Owls: Oswald, his brother Hoots and an unrelated owl called Fat Owl which is the constant companion of Mayor Brian Snailton III
Turtles: Zoom, Boom, Myrtle and Sheldon
Hedgehogs: Scruffy, Snuffles and Senor Hedgelino
Hippo's: Harry and Hippurtle
???: Bork. Really I have no clue what species of animal he is supposed to be.
I'll stop there, around the halfway mark. There, my madness is laid bare.
