Timet distributes so many potions each year, that he decided he would try out one of his holiday favorites. In order to maintain a mundane existence, Timet likes to disguise his options as normal looking bottles of alcohol, though there was always some way to identify each one. He pulled the bottle of Jaegermeister, the normal image of a deer replaced with a more festive reindeer. Taking a deep swig, he made it sure that the burn of the alcohol his the shifting of the body as it changed from his normal wolf self to that of a reindeer. The afterbuzz of the alcohol helped bring the drinker back down from the change. After his mind cleared from the gulp, Timet inspected his new festive form, enjoying what he saw.
