Tube creature
Appears in	Mario Artist: Polygon Studio (2000)

Tube creatures are large, flying oblong shapes that appear in the Jikken World in Mario Artist: Polygon Studio. When approached by the player, a warning sign appears on screen and the creature slowly moves toward the player's creation while making a guttural mumbling sound. If the creature makes contact, it will eat one of the creation's parts, preventing the player from using it until the next time they enter the Jikken World. Like the flying egg creatures, tube creatures are invincible.

A single tube creature appears flying above the lake entrance to Porigoneshia. Another two appear in Kūchū Teien Porigonā, one in the large tunnel and one in the Aquarium na Gogo sub-area.
