Belltrio flowers bloom in a trio of colours in an effort to appeal to different Bug-Type Pokémon. The nectar their three flowers produce have different flavours; one being savoury, one spicy, and one with a mild numbing effect.
Because the triplets originally split from one body, they think exactly alike. A Belltrio's thin and flexible body lets it bend and sway to avoid any attack, however strong it may be.
