^ I believe that it is electricity, basically the same way that animals like the Electric Eel function.

Living bodies generate a small amount of electricity, passing between the cells and as part of the function of the nervous system. That is the reason electrocution is so dangerous, because it disrupts the normal signals. Some species in real life can generate electricity in amounts that are useful, such as Electric Eels.

It seems like they're able to basically generate voltage inside their RC cells, and then discharge it through the Ukaku.
