For its nest, PHANPY digs a vertical pit in the ground at the edge of a river. It marks the area around its nest with its trunk to let the others know that the area has been claimed.
Sapphire:
PHANPY uses its long nose to shower itself. When others gather around, they thoroughly douse each other with water. These POKéMON can be seen drying their soaking-wet bodies at the edge of water.
Fire Red:
As a sign of affection, it bumps with its snout. However, it is so strong, it may send you flying.
Leaf Green:
It swings its long snout around playfully, but because it is so strong, this can be dangerous.
