Io, the Winter Wolf

This small jet figurine fits easily in the palm of your hand. Its origins are unknown.
As an action, you may toss this figurine onto the ground within 60 feet of you and speak its name. If there is space available, it transforms into a fully grown Winter Wolf named Io. Io understands the same languages you do and will obey commands to the best of his ability. Io must return to figurine form at least 8 hours every day.
