This blue-colored Pokemon looks like a tadpole and it has a white belly with a red spiral design on it. Its eyes are round and its arms and legs are fin-like, being slender and small. To color this Pokemon, I would start with a light or medium blue background, using a darker shade of blue for an elevated level of detail. For the eyes, I would use perhaps a dark purple, along with a darker colour of red for the spiral design. For the belly, I could use a combination of white and light yellow for an interesting effect. For the small arms and legs, I would use a blend of light pink, light purple and light blue. Lastly, I would use black to outline the whole image, enhancing the general design.
