Katrina jumped slightly at the professor's transformation. This could take some getting used to, she thought. Okay, time to pick an animal! Let's see......she'd never liked too much of the cute cuddly animals anyway...... and why not take a risk? Aiming her wand at the small sweet in front of her, she said," Tiger Snafius Danium!" Grinning, she took the sweet and popped it into her mouth. She watched as a wave of orange and black spread over her skin, and soon enough it covered her whole body. Little tingles in her mouth informed her that her teeth had sharpened slightly. Cool! she thought, a little tiger grin on her face. Okay....and the fur should fall off in a couple seconds after this. Katrina waited, one second...... five seconds....ten..... fifteen........ twenty- why wasn't she changing back to her normal self? As it ticked past forty seconds, she began to panic. Thankfully, a second later, her fur began to fall off, and in a few seconds she stood there, normal, human Katrina again. That..... was scary, she thought. Raising her hand, she said," Professor, is there any chance of the spell becoming permanent if we don't use it properly?"
