Toothy Deer is one of Roblox's classic mascots/home characters. They are seen in Roblox admin Shedletsky's video "Online Social Hangout", hiding from people because they were calling them a toothy deer.

In this game, they are a mage healer that uses magic to heal and amplify damage; so I expect them to just sound a little fancy- like a royalty sorta deal?
I also think it would be funny if they said words real funny, like "I am noth a toofy theer!" to exaggerate the fact that they have toothy deer teeth. This may/will likely not sound that good in practice, so it is recommended that you do a take without this.
