I'm afraid I don't know what this creature is, and its name is purely speculative. Making overworld sprites showing it from the back and sides has only brought more questions. This is okay. Questions don't always need answers. As usual for this series, I took a randomly-generated 7x7px sprite and interpreted it into a creature. The rules are:

• The detail sprite must fit in a 64x64px canvas
• That includes a one-pixel black outline
• The palette is three colors plus black and transparency
• Three colors are randomly generated, but I'm allowed to change one to a color of my own choosing (I'll show the original random colors in the prompt, below)

Prompt:

The prompt had two nearly-identical yellows, so I immediately chose to throw out the more greenish of the two for the darker blue I knew I'd need to get smooth round holes on the face.  I was initially planning to make this one much taller and more imposing, but I've given myself a strict maximum canvas of 64x64 for each detail sprite. It came down to making the body and horns smaller or sacrificing the face/mask detail, and I'm glad I went for more childlike proportions in the end.

EDIT: Now with an idle animation! And yes, my fellow autistic pixellers, they are stimming.
