Otis is mute, and therefore has no way of speaking.
However, he can still communicate, and does this through speaking in jumbled symbols.

Like actions in the game, each symbol can mean more than one thing depending on the context in which it is used along with whether it is repeated or not. Most symbols have a straight-forward meaning and some cannot even be directly translated.
I try to make his speech relatively easy to understand. Feel free to ask for translations.
