|Fastidious J. Spiffington|
|First appearance||"Neat Freak"|
|Residence||Fastidious's giant bowl|
Fastidious J. Spiffington is a small hamster with a cultured British accent, obsessed with cleanliness and world domination. He is nearly always seen inside a hamsterball that serves as the control center for his robots, mainly his Hamsterbot. He has a habit of drastically increasing his pitch whenever exclaiming certain words, such as "Activate!!". He seems to be a certified attorney.
When Pondscüm was turning into a frog, The Blixens left him and he shouted where would they find a small animal with a strange accent in a clear container hooked up to a robot, Fastidious was the first person that came to mind.
