Dipplin is a worm-like Pokémon that lives inside an apple. In contrast to Applin's other evolutions, Dipplin bears a strong resemblance to Applin. Unlike Applin, however, Dipplin appears to be composed of a pair of separate bodies; the head and tail visible outside of Dipplin's apple appear to belong to two different creatures. The head belongs to the "fore-wyrm" while the tail belongs to the "core-wyrm." Both of Dipplin's bodies are light green, with a yellow-green underside. The fore-wyrm's head has two large yellow leaf-like eyestalks with small black pupils, and a tall, thin protrusion similar to a horn or an antenna. The core-wyrm's tail that sticks out from Dipplin's rear has two leaf-like features on it.
Dipplin's evolution is said to have been triggered by the exclusive Syrupy Apple of Kitakami. The pair that composes Dipplin works together inside their shared apple. They are capable of producing syrup, which they use to coat their apple in layers. This syrup has a fragrant scent that captivates Dipplin's opponents. They can use the syrup to engulf their opponents and hinder them.
Dipplin itself resembles the Gigantamax form of its evolutionary relatives, Flapple and Appletun.
Despite it not being known to evolve into any Pokémon, the Eviolite works when held by Dipplin.
Dipplin, like its evolutionary relatives, appears to be based on the popular image of a worm burrowing into an apple, as well as a pun on the wyrm, a type of dragon — hence its Dragon typing. Dipplin also appears to be based on a candy apple, which is made by coating apples with a sugar mixture, and is often served at festivals and holidays. Dipplin's Shiny coloration seems to draw inspiration from the similar treat of caramel apples.
Dipplin may be a combination of di- (prefix meaning double), dip, and Applin.
Kamicchu may be a combination of 果 ka (fruit), 花蜜 kamitsu (nectar), 虫 chū (bug; worm), and カジッチュ Kajicchu (Applin).
