CLAMP in Wonderland 1994 Summer is a short printed fan comic (Dōjinshi) based on Stardust Crusaders, written and executed by famous manga studio CLAMP before their professional fame. It is a gag story with BL overtones and is well known in the JoJo fan community, the opinions on it being very varied. The book also features comic strips based on other franchises.
Kakyoin wakes up one morning to discover that he had "laid" an egg and reveals it to his friends. When his friends discover this, Joseph asks when his grandson will be born (thus turning Jotaro and Kakyoin as a romantic pair canon for this dōjinshi).
The child suddenly hatches out of the egg to reveal a star-shaped birthmark on his shoulder. Thus concluding that Jotaro and Kakyoin produced an egg. Out of courtesy for Joseph Joestar, they name the small boy who hatched out the egg Jota Kujo (空条丞太 Kujo Jōta?). The child, it would appear grows faster than a normal human and within a week he is able to attend school.
In a jealous fit, Jotaro attempts to fight Jota. Jota suddenly activates his Stand, which looks like a more "chibi" version of a green Star Platinum. Polnareff comes up with an idea to have Jotaro name Jota's Stand because he was "too lazy" to do it himself. In annoyance, Jotaro walks over to the kitchen to bring out green dish soap, saying the name of the brand, "Charmy Green."
- In the Clamp in Wonderland music video series, a younger Jota and Charmy Green, along with an older Jota, can be seen at the end of the first music video, right before the credits.
- Other JoJo-related involvement from CLAMP include their submission for the 25 Years With JoJo anniversary project, as well as Araki's interview with Tsubaki Nekoi.
