Eldritch Abomination Synthesist Summoner help

[Chimera245]

I have a Summoner character from Pathfinder's Advanced player's guide, using the Synthesist archetype from Ultimate Magic. Her Eidolon is an HP Lovecraft-inspired unspeakable-horror-from-outside-the-universe. And since she's a Synthesist Summoner, she more-or-less becomes, the summoned creature, rather than having it pop up in a square next to her, using her own body as a means to channel it into this dimension.

I've decided i was tired of being vague with what she/it looked like, so i decided to draw a picture.

Here's my problem, and the whole reason I'm posting this:

I can't figure out what to do with her arms! Every other part of her has turned into a gaping maw or creepy eyeball or mass of tentacles or something. (Since I'm level 2, most of this is just cosmetic until I can afford to spend evolution points, of course...) But her arms are kinda just sticking out behind her looking useless...

What can I do with them?

Anybody?

If it helps, I've already turned her head into a gaping maw with a horn on the forehead, her mouth into an eyeball, her pigtails into giant snakes, her chest into a kinda dragon looking snout, her thighs have creepy bug legs coming out of them, which support her in this form, and her lower legs are a bunch of tentacles.

But I still don't know what to do with the arms. Turning them into wings just seems "too easy".

More joints and longer fingers?

You mentioned tentacles or something.

What about having her arms separate at length and each part become a tentacle thing? (so the tentacles would have a nail on the tip or couple fingers sticking out in a very disturbing way)

Ever watched S-cry-ed? If yes, think of Kazuma's initial arm transformation.

If not...well, I couldn't find any picture of it, but there are episodes on youtube, I don't remember now since it was so long ago since I watched it, but I'm pretty sure it happens in episode 2 or 3, so look it up.
