Rosebud is a hamster and only appeared in Horrid Henry's Perfect Protest. Fang was going to take part of the Fearless Phantom movie being the man eating hamster from Mars, but got fired by the important director due to Fang being too greedy, so the director replaced Fang with a different hamster. Henry and Fang check out the other hamster when Fang met Rosebud and that they both have a crush. At the end, Fang and Rosebud hold hands together, showing their shadows. It is not clear what became of her, but she might have been adopted by one of Henry’s friends or enemies or teachers.
Rosebud is a light brown hamster. She has brown eyes, a pale belly, a pink bow tie, and bucked teeth.
