This is Popcorn! This character was designed by Dr. Kaizer and is one of their Gremlin species.
Popcorn is kind of jumpy, scared easily, anxious/panicked, but always trying to scare everything else. He's kind of cat-like in that respect. He adores Spooky: https://www.weasyl.com/~scribbles/submissions/35003/spooky-third-eye-tripp-or-treating
And is much more stable when they're around.
He also has a shy younger sibling: https://www.weasyl.com/character/44095/phantom
