Squirtle: A bit of a challenge since Squirtle is shown as both a biped and quadruped in the anime. After a lot of feedback to make Charmander biped (who is never quadruped in the anime), I decided to depict Squirtle as a semi-biped Terrapin (Fresh Water Turtle). I had to change the features but I can only speculate a Squirtle would probably use all fours most of the time and chill on its back legs for a better look at its surroundings.
Totodile: No brainer; baby crocodile. It was really hard to even make it biped so it's on all fours now.
Piplup: Baby Emperor Penguin.
Oshawott: Sea Otter Pup with a Beaver tail.
This is just how I interpret Pokémon if they were 'real-life' or 'realistic.' I understand that people don't agree with my interpretations, but instead of getting snarky about it you can always find another artist to draw Pokémon the way you see them Hope you like them guys!
