Groot pauses in his search and looks at Tobias, "I am groot." He says sounding maybe slightly hurt you think of him as such. Then keeps searching for Sunny.
Sal you need more languages thats not nearly enough. lol. Even Groots Sylvan is subpar. Almost childish, he was lost to his people at a young age and common is very hard for him to form with his mouth. So he only has 'I am groot' down.
"I am groot" Groot says very concerned that sunny vanished. He wanders towards where she was with his arms spread searching for her. A strange wind blown sound comes from him. "I am groot."
