Used the sprite sheet as a template for characters in my (abandoned) game https://chaoswitchnikol.itch.io/kozy
The Goat Characters sprites are available here https://chaoswitchnikol.itch.io/goat-characters
And here are the enemy characters for the same game https://chaoswitchnikol.itch.io/animal-characters
The only real change(s) are characters' heads and colors
In the most of them the "belly" part is using the same color as the rest of the body.
Some of the charactes do have shortened tails.
The ears act in tandem with the tail - ear goes down on the same frame as tail and then stays there for one more frame

Aseprite to design the changes of the characters' heads and Gimp to swap the color palettes
(disclaimer: I'm not that well-versed in either of the programs, so I used what I knew a workflow for, in order not to not waste time)
