Bottles is a gentle, meek mole with a lot of knowledge. While generally non-confrontational, Bottles can get agitated from time to time, as shown when the player repeatedly talks to him at the first molehill in Banjo-Kazooie. Bottles is also not afraid throw back banter when it comes to Kazooie's badmouthing.

In Banjo Tooie, Bottles is shown to be a bit oblivious to his surroundings as he is the only one that ends up getting caught in the deadly blast of the witch's spell.
