- His name is a pun on the edible plant cucumber.
- Before his debut in the main comic, Q. Cumber was the "Co-Host" of a short-lived feature in the Sonic Super Digest series known as "Professor Pickle's Nature Notebook", in which he and his boss, Professor Pickle, examined the real-world animal counterparts of many Mobian species. Interesting enough, his name during the feature was simply "Cucumber".
- His full named was revealed in the Off-Panel from StH #258; while Professor Pickle and Professor Charles the Hedgehog were aboard the Egg Train, Charles while worried for Ben Muttski's safety asked Pickle if his assistant was safe as well. Pickle calmly told Charles that he instructed Q. Cumber to check on his new girlfriend before they were kidnapped, ensuring his safety. Q. Cumber is later seen visiting Pickle's hideous girlfriend (Mama Robotnik from Adventures of Sonic the Hedgehog in a pickle costume) and giving her flowers and candy on Pickle's behalf, much to his displeasure
