Here we have Ben's alien SlipShine

Tricalcites are a race of beings whose bodies constantly produce a substance that had a similar chemical composition to soap. As such, this leaves their body generally slippery to the touch, with many things able to just slide off of their body instead of clinging to it.

The soap-like substance creates a layer of suds around the Tricalcite’s body, which can be manipulated and condensed to give them an easier time grabbing onto things without the worry of it slipping out of their grasp. Moving around can also become easier with a layer of suds encasing their slippery bodies.

Tricalcites live in moist environments, as their bodies are capable of drying out easily and preventing them from secreting their bodily fluids. If they lack moisture, or are in places that are too dry or hot, they run the risk of overheating and their skin cracking. On the flip-side, if they’re in an area with too much water, they’re unable to form a layer of suds around them, leading to them feeling vulnerable and embarrassed.

Due to having bodies that are similar to soap, Tricalcites are very good at cleaning dirt and grime; their secretions actually being a favored addition to cleaning products. However, it’s not recommended to use the substance to clean one’s body without heavily diluting it.

Not only do a Tricalcite’s secretions have a cleaning quality, but a secondary chemical compound located within is capable of neutralizing a person’s abilities for a certain amount of time, leaving said person defenseless… as well as making them slippery.

Tricalcites are also capable of creating and blowing bubbles that can be used as projectiles
