Komboo

Komboos are walking -like creatures found in the Lake Kingdom of Super Mario Odyssey. They are normally found in chasms in Lake Lamode, and if Mario swims to their spawning point, they will emerge and start walking in a swaying motion towards him. Mario can simply throw Cappy at them to take them out; however, they will keep spawning from the same position. Komboos also cannot be captured.

Trivia
Their name is likely a reference to kombu, a variety of seaweed used extensively in Japanese cuisine.
