Twidash fusion

I don't feel like the Rainbow Dash part of this is very visible but oh well.

Basically, I've been having this idea developing in my head for a little while now...It's basically like a gem fusion from su, but with like...Ponies lol.

I haven't worked out the full details of it yet, but the general idea is: It's a spell, and can only be performed by either alicorns or very magically advanced unicorns. However, there can be any other species of pony included in it, even griffins (Although it's MUCH harder to fuse with a griffin than any other pony). The spell also has to be accompanied by a dance, like ordinairy fusions.
Also, since it needs a spell to happen, accidental fusions (like Steveonnie was) are pretty much impossible.

Other than that the same sort of fusion rules that apply to gems sorta apply here.

This is on a white background instead of transparent for now, bc it's late and I wanted to upload this before I slept so I needed to upload it quick. I'll sort it out tomorrow, and maybe add a few extra details to it.

For now though...Yeah that's pretty much all I have to say.

**EDIT** made the background transparent. I'm too lazy to add any other touches to it though lol.
