I have a vague recollection of some sort of cartoon in which a (pink?) girl is sent on missions in some sort of other dimension. I remember she has a friend instructing and helping her out; I think it was a boy with some sort of computer. They had a link between the worlds so that they could communicate. I remember just one scene, where the girl was sprinting towards the portal away from the dimension, but she was running out of time to escape?..
The cartoon was in English, and probably aired about ten years ago.
I'm so sorry if this is too vague to be answered, but it's been driving me crazy for weeks! Many thanks to anyone who knows what I'm thinking of.
