Rushlet

Rushlets are a variety of mushlet debuting in Tunnels from Nowhere. They have a similar body to mushlets, but are most notably spherical as opposed to having a foot and have vibrant cyan colouration. Unlike their base variant, rushlets are known for their higher speed but slightly less durable bodies. They can also cling to and roll up walls, although this attribute is not shown in their debut game.

Their name comes from "mushlet", only with the first letter swapped to an "R" such that it contains the word "rush" in reference to their tendency to move fast.
