Keswick

Keswick is sapient humanoid species native to planet Keswickia.

Description
 

According to their anatomy, they are semi-aquatic aliens. It is possible that two of their three hearts pump blood to his gills while the main heart pumps blood to the rest of the body as in cephalopods. This alien species also has a super sensitive nose requiring them to have stink police on their planet. Keswickian Police was chasing individual called Keswick Jr. for cooking stinking fish at work which forced him and his family to leave his planet and universe and moved to Earth. Leaving Keswickian universe could cause its annihilation, but that could have just been a lie as Keswckia is actually a planet.

This species has a metamorphosis that causes them to change appearance during their maturation stages. As babies, they look like small mudskippers. Later as older children thay have a platypus-like form and shoot barbed quills when they hiccup. As teenagers, they look almost like their adult form except that they have lizard tail and are able to squirt ink from it. As adults, they have dog/rodent-like form, and as elders, they look like jellyfish.
