Bonnie from AFK Journey.
Unfortunately, I can't get it to do her little hat consistently, it usually creates a big one. If you can get the right size please share the prompt ^^

Recommend weight of 1.2. Even though it technically works at the default 1 and is more flexible with styles, it's a lot closer to her looks at 1.2 (can go as high as 1.5).
Add "3D, 3D art" to the negative if you want purely 2D results, otherwise it will try to mimic the game's 3D look (last example image)

Copy the recommended prompts or just experiment with it!
