Enhances her shapeshifting

Doppel rushed over to the book and began writing in it.

Doppel's Shapeshifting abilities have advanced to the point where if she shapeshifts into an Extraspecies, she can access all that species traits and abilities in addition to her doppelganger skills.

She was feeling giddy at that. She had potent shapeshifting skills, but she couldn't just get Tio's enhanced strength or the ability to come apart like Zombina, not to mention all the other races.

"Let's see what I can do!" She says excitedly, making sure to lock her door.

Lamia

Doppel tried becoming a lamia, and watcher legs coil together and lengthen into a long tail. She could do that before, but after getting the tail, she felt very different. "Brrr..." She said, suddenly feeling the cold blooded side effect of being part snake. "Didn't mind the cold so much before." She wraps her hair around her torso, her yellow irises following tail all the way down to the base.

"I'd heard that the tip of the tail is quite sensetive." Doppel's hair snakes its way (heh) down and squeezes it lightly. "Ahhhhn~!" She lets out, feeling the rush of pleasure. "that was intense..." Panting, Doppel decided to take a break... after one more squeeze.

Harpy

"Doppel is a harpy is what Doppel is!" She says, snickering at her impression of Papi. That harpy could be such a ditz. Doppel looked over her fluffy wings and new talons as she briefly took off the ground with a couple flaps. "Neat, I might need to get used to flying.

"Nice!" She said before hearing her belly rumble and looking over at the waffle. "Guess I could use a snack." She said, taking three steps towards it than paused. "... what was i doing?" she looked around and spotted the Sex note. "Oh right I was playing with that." Three more steps towards the sex note... "What was I doing?" She looked back at the waffle. "oh yeah, getting some food." Three steps. "What was i doing?"

It took her 15 minutes to escape this loop by remembering she could use her hair.

Ogre

"Hehehehe~" Doppel looked like the spitting image of Tio, except for her hair and eyes, both of which the shapeshifter kept the same. "Tio's got the milkshakes to bring the boys to the yard~" She said, bent over and waving the tits in front of the mirror. she also took the chance to spank her ass, feeling both her new strength and durability. "Real shame about that Interspecies law stuff about now having sex, she'd have so many offers~" Doppel chuckled, before looking over at the note. "maybe i can fix that..." She walks over to the book.

Or she could try out some other forms~. She hadn't tried the ones with the cool powers yet, like a devil, slime or Yuki-onna yet...
