A gemstone that filled up with magic, huh? The golden script on the Piano's side that served as its eyes gleamed. It was not against searching for magical items--could keep some of them for myself too, if they're useful-- but it was... interested by this. Plus, it was rather curious on the effect that its spells would have when not used on itself. It had never encountered anything like this before.

Say... would the catalyst itself grow teeth when imbued with The Piano's biteforming magic? It idly tried to find out, only to give a keysmashed chord of pain when the teeth sprouted where they were not supposed to. Fangs sprouted from the wood of its body, forcing the material apart and causing cracks to splinter through its beautiful polished boards. Unbelievable! This had never happened before.

The Piano glanced at the star-spangled creature beside it, who was also casting spells. It hoped it would not be judged for the failure. It disliked public failures very much.

Trying to look nonchalant as much as a piano could, it thought through the rest of its limited magical repertoire. Producing venom didn't sound appealing when there were myriad teeth sprouted all over their body that the venom could accidentally end up, so it went with something simpler. A spell to sense heartbeats didn't have quite as much interesting experimental value as growing teeth, but it was safe, at least.

Magic flowed into the stone successfully this time, and The Piano breathed a sigh of relief. It could feel the botched magic of the bite-forming spell weakening, and the pressure on its newfound cracks easing. Newfound confidence flowed through its elegant nine-foot-long form. Perhaps it should try something more challenging.

It had learned a new, powerful magic after consuming a chocolate candy, once. Staring at the catalyst, it thought it might be oddly appropriate to bestow the magic of one inanimate object upon another. Humming softly to itself, it let more magic flow from it into the stone. Powerful, but barely controlled--but as long as it was successful, what did it matter?

Its confidence and curiosity renewed after numerous successes, The Piano decided to try the teeth again. The flow of magic continued, but the catalyst, as far as it could see, did not grow teeth. Oh, well. It had more or less learned the pattern by now. It didn't really matter what magic was cast into it, as long as it was magic. And the more powerful, the better. The different spells were just a vehicle, really.
