You picked the kaiju option...uh oh

"Uh, don't be mad but I picked the kaiju option." "What?! Why didn't you pick the safer option like an anthro tiger or something?!" "I was curious okay!" Tigra then grunted as she could feel the transformation kick into affect. You backed up as Tigra began to grow in height. You sweat dropped as she steadily grew from 6 ft. to 8 ft. to 10 ft. and so on. Her height eventually reached almost 20 ft. tall. Tigra then had to crouch so she wouldn't burst through the ceiling. She then felt the next change commencing as her muscle swelled causing her to groan. "Fuck, why does this feel so pleasurable!" You watched as her body bulked up with muscle until she looked like a female body-builder. Next, her nails grew longer and longer until they looked like they could claw through steel. The same thing happened for her nails on her toes. After that her tail thickened and lengthened making Greer having to wrap it around herself. "Grrrr. Can't you revert the changes?!" "I can't! The change has to be complete before I can revert it." You told her as her transformation continued. Greer began to moan as she felt two pair of breasts begin to grow and develop under her original pair. When her breasts eventually stopped growing, she had six large breasts. Her transformation went on as her face pushed out into a feline muzzle as her teeth sharpened and her orange-red hair lengthened and became more wild. With her changes complete, Greer was now an almost 20 foot tall anthro tiger. "While it was enjoyable at first, can you change me back? It's kind of cramped right now." She groaned as she tried not to move unless she wanted to break through the ceiling or walls. "Alright." You say as you touch Greer making the menu pop up. You scroll through the menu until you find the option to revert the changes. You pressed the option but a problem occurred. A message popped up saying, "ERROR: Can't revert current changes." "What?!" You say in disbelief while trying to press the option again only for the error to pop up again. With a groan, you close the menu. "Well, did you revert the changes?" Greer asked you with hope. With a heavy sigh, you inform Greer. "Okay, don't be mad but the bad news I can't change you back." "WHAT?!" She shouts causing you to cover your ears from how loud she was. "I tried to revert the changes but it gave me an error saying that it can't revert the changes. I don't know why it's doing this. It's never gave me that error before." You groan as you sit down. "Great, I'm stuck as a giant anthropomorphic tiger now." Greer groaned. As you sit in wonder of what to do next, something happens.
