This colorful Pokemon has blue scales that glimmer in the light. Two thin fins sit atop its head, and its eyes are small and beady. It has a large tail fin that flares out behind it and a small mouth, giving it a uniquely puckered expression. To bring out its features, I would color the head and tail fin with a darker shade of blue. Meanwhile, the scales can be filled in with a lighter, brighter blue that gives the creature a glossy, almost gemstone-like appearance. Finally, I'd add touches of white for the fins and eyes to make it come alive.
