Floaty and Jumper-shoot are both in Kirby’s Dreamland 2, but only Jumper-shoot made it to Kirby’s Dreamland 3 (as other enemies made up for parasols). Floaty is just a small adjustment to the normal parasol that was used in all the Kirby games before. They accompany some Waddle Dees and help them gently float through the air. Once they landed, Waddle Dee usually let go of Floaty, allowing floaty to either fly away or tackle Kirby. Jumpershoot, is a mini boss in both games. He jumps around on one foot and spins himself around to make himself dangerous. He occasionally kicks his sandal off too, but Kirby can use his sandal to hit him if Kirby exhales it.
Both of them are spin-offs of a Karakasa – a form of Japanese ghost. They are pictured much like Jumpershoot already is, with a single eye, long tongue, and a foot where their handle used to be. Karakasa love rainy days, surprising people and listening to jokes, but they don’t like people who do not believe in ghosts and the absolutely HATE people who do not like to have fun. The class of ghost that a Karakasa is categorized under is a Tsukumogami.
Roughly translated, it stands for “artefact spirit”. When useless objects reach their 100th birthday (or year of existence) they will animate and become alive and aware of their surroundings. The origin of the item and condition of the item on its birthday will predetermine how the ghost will appear and act. If an old paper lantern has tears in it, it will use those tears to create itself dark eyes and sharp teeth, thus becoming a scary monster in appearance. If a tea kettle is kept from becoming rusty and is always nice and polished, it might adopt a more pleasant visage.
Tsukumogami are forms of legendary beings. Even though Tsukumogami are harmless, they occasionally like to pull pranks on people. Much like the Karakasa, they love to have fun, but they may also like certain other things depending on what object they are. They can get angry however and will band together to take revenge on those who are wasteful or who have thrown them away thoughtlessly. A Jinja ceremony can be held to console objects who are about to be thrown away. Modern Day objects cannot become Tsukumogami however. Tsukumogami are told to not be able to withstand electricity of any kind. Common gathering places for Tsukumogami are junkyards.
Tsukumogami that have official names (like the Karakasa) were usually featured in an art production during the Edo period of Japanese History, around the same time legends of them started to originate. There was a trend among certain artists to paint certain Tsukumogami. This seems to be where people got the idea of what certain objects look like as ghosts.
