"Bidoof is seen as a kind, helpful Pokémon, that is loyal, and will believe his friends, as observed when he was the first to declare that he believed the player's partner's story about Dusknoir. His lacking experience at exploring and status as one of the most junior members of the guild is a recurring element in his character portrayal, and gets him into trouble multiple times, such as when he reveals the guild members during the player's graduation exam. His big appetite is noted on several occasions. He often uses the interjection "by golly", and frequently punctuates his dialogue with the phrase "yup yup", which he also includes in the title of his diary."
