Instructions for use: Place in a filled bathtub or hot tub, wait for it to fully dissolve, then fully submerge for a minute. Effects last 24 hours.
Warning: Do not use if pregnant. Discomfort is normal, but if you begin feeling pain, leave the water immediately.
Setting the brief instruction guide aside, the lizard looked down at the enchanted bath bomb in his hand, before dropping it into the tub. Before long, the bath bomb had fully dissolved, tinting the water a light blue. Once he'd gotten in the water as well, he felt a tingling on the parts of him that were under it... But, nervous from anticipation as he was, he remembered what to do, and took a deep breath before laying down in the water.
The lizard stayed still, as the magic gradually did its work. His scales changed their angle, softening and growing into feathers, and his nostrils were blocked for a few seconds as a beak extended from his face, before its own nostrils formed. His tail retracted away to nothing, before more, larger feathers fanned out in its place. At the same time, a more intense tingling spread along his legs, changing them to fit the bird form he was slowly taking on, and he felt a few painless clicks as the bones in his feet adjusted to make those feet into talons.
Soon, the feelings faded, and the change was done. The new bird sat up and exhaled, before looking over his new body. He let out a satisfied chirp, eager to see what it'd be like to spend a day in this new form.
