I named most of the female pets after characters I created myself because they kind of resemble them, but some of the names I made up are:
Ice Wolf = Sub-Zero
Wizard Elephant = Big Top
Tundra Reindeer = Agustus (He looks like the type)
Bamboo Panda = Po (thanks Kung Fu Panda)
Greedy Dragon = Iblis
Boatman Salmon = James (this may sound silly, but it's based heavily on AVGN's "Board James" series. I keep wanting to call my Boatman Salmon, "Boatman James")
Water Dolphin = Neptune
Star Tree Buffalo = Maximillion (I'm keeping him a Juvenile)
Lightning Hedgehog = Raimoundo (he reminds me of Rai from Xaiolin Showdown)
Gladiator Horse = Cliff
Quake Gorilla = Earthlink
Karate Dog = Flint
Laser Chameleon = Eyeball (cause of that eye thing he does)
Electric Lion = Zeus
Wild Wolf = Boskov (he reminds me of a Russian Soldier in his Juve form)
Cranberry Rabbit = Cranberry (I didn't like the original name it gave her)
Clam Otter = Ollie (just fits....)
Dark Sabertooth = Shadina (the only truly original name I came up with)
and Knife Hamster = Ghengis (cause he looks like Ghengis Kahn)
As for my females:
Shopaholic Kitty = Amoura
Leaf Deer = Pheona
Flower Frillzard = Psylence
