Bubble Plant

The Bubble Plant is a blue plant that resides in the west area of Flower Fields, in Paper Mario.

The plant rests right beside a large pit full of dangerous vines. The Sun Tower lies on the other side, and Mario needed a way to get there. Soon he spotted the Bubble Plant, a mysterious plant who constantly blew bubbles into the air. Upon speaking with the plant, it told Mario that if he gave it a Bubble Berry, it would show Mario the real reason it was called a Bubble Plant.

After Mario found a tree that grew Bubble Berries, he handed one over to the Bubble Plant, who, satisfied with Mario's deed, blew an enormous bubble that was big enough for Mario and his partners to hop in. It then flew over the large vine pit until it reached the other end - from there, they could access the Sun Tower.
