Very territorial.
Cataquacks are ducklike creatures that live on Gelato Beach and are easily angered. When they get angry they hurl Mario into the air, and sometimes hurt him.
In Super Mario Sunshine, Cataquacks come in two colors, red and blue. The blue Cataquacks are harmless, but the red Cataquacks will inflict damage to Mario.
In Mario Kart: Double Dash!!, Cataquacks are revealed to come in purple and green varieties, in addition to the other red and blue colors.
