So Darny and Ethan start to become bros and he found out about goo Darny (who is he own Darny form the changed world but Darny can change to it to fit in if he visits the goo world he got this power not too long ago to fit in for this pic) After a bit of experimenting, Darny managed to give Ethan a new Gooey form. Looking similar to Darny’s goo form, Ethan has a bit getting used to his new form, though at least the transformation is temporary. In the meantime, the two of them are going to enjoy some time being gooey together and Ethan got a new form to change into and even get to keep his colors even if he a black goo.
