Gooble

A Gooble, originally known as a Swoopin' Stu, or Name Kuri, is a type of transparent creature that appears in Super Mario Sunshine. Goobles can be found wherever there is goop. They were previously named for the Strollin' Stu, but they do not closely resemble Strollin' Stus, instead appearing as round slug-like creatures. They come in a large variety of colors, as well as some size variation, although they all act exactly the same. For the most part, unless Goobles see Mario, they generally wander in an outward direction without any real, apparent purpose and do not create a larger "goop area" unless they fall off a ledge and pop on impact. Petey Piranha's goop is also capable of creating Goobles.

Once a Gooble spots Mario, it turns white for a second before making a "bwooww-wop" noise and performing a kamikaze jump towards his location, leaving goop behind. Goobles appear prominently during battles with Gatekeepers, spawned from their base, swooping at Mario whenever they have the chance and disrupting his own attacks on the Gatekeeper.

Goobles can be destroyed with a blast of water from FLUDD or by being jumped on, though the latter method leaves behind a puddle of goop that can spawn more Goobles. This can be avoided, however, if they are jumped on while they are in the air. Stomping on them also causes them to occasionally drop Water Bottles. Eventually, Goobles pop even without provocation but do not leave goop.

Goobles were originally intended to have a more slug-like design in the game, but their design was changed in the final version.

In Mario Golf: Toadstool Tour, the name "Gooble" can appear on the leaderboard.
