Other characters

Rosalyn is Calvin's baby sitter and a senior in high school. Calvin thinks she is evil, but she is only strict because he never behaves. In her final appearance, Calvin behaved and she was nice, mostly because she agreed to play Calvinball with him and Hobbes.

Rosalyn also appeared for a short amount of time as Calvin's Swimming lessons instructor. She also has a boyfriend named Charlie. Calvin, on one occasion, picked up the phone on the same line while Charlie had called Rosalyn, and proceded to tell him to break up with her and said she was a "sadistic kid hater".

[edit] Rosalyn's hair color

In the only appearance of Rosalyn in a Sunday strip, we see Rosalyn with blonde hair. However, in the tenth anniversary book, we see a brown haired Rosalyn in the characters section. Since Rosalyn's hair is not coloured, the intention of a dark hair colour can be dismissed.
