Fanon
Cream Machine is a rarepair within the RWBY fandom. Due to the lack of interactions between Neo and Penny and the unlikeliness of them even becoming friends this ship is considered a Crack Ship but even with all that there are still a few fans who like Cream Machine among the RWBY fandom, the ship was mostly popular around Volume 2 - Volume 3, but lost popularity at the end of Volume 3 due to Penny being disassembled in the Volune although when she returned in Volume 7 few people began finding out about the ship and the pair increased in popularity, though not that much there were still a growth in the ship's popularity.

Some fans still hope for them to become at least friends in the RWBY series

RWBY Fans who don't ship Cream Machine will likely ship more popular pairings such as Gelato, Baked Alaska, Mint Ice Cream, Strawberry Shortcake, Spicecream, Nuts and Dolts, Gingersnaps and PennyWeiss.

Cream Machine also has currently 5 fanfics on AO3
