BB raised her tentacular arm with a frown, still shaking it gently as though she could force the appendage to change to its usual form.
"Hardy har har," she said to Raven's joke, her other hand probing the same as her friend's fingers. The flesh felt different from the rest of her arm; smoother, more elasticity, almost like it was silly putty. She could feel the prods and pokes, which made her shiver, even as the arm seemed to writhe of its own accord.
"Yeah," she added to Alice's semi-explanation. "We've...I've had a couple of dreams where I was...this thing." Something in her head went hmpf as if offended. "It kept changing shape. All kinds of stuff, too, not just like...physical things. Maybe you're right, skittles, maybe I can..." She squinted her eyes in concentration at the arm, willing it to change back to how she'd been before. Then she could feel it, and the barest trace of hope crossed her face.
Her arm started to shift before them, but instead of changing back to its slimmer, tawny-colored former shape, it turned a burnished red that faded to white on the underbelly. The tentacle reshaped itself to something larger, and heavy. BB tipped forward slightly as it became a huge crab claw, her other arm slipping under thick exoskeleton as if she could hold the thing aloft.
"Um, that's not what I wanted," she whined at her arm, as though they'd gotten lost in translation.
