Does anyone know of a childrens book about a girl who, when left alone in her house looked through the wrong end of her fathers telescope and got transported to another world. In this world I seem to remember there being a short man with four arms wearing an orange fur coat and a wannabe superhero who wore green tights. The girl made friends with these characters who helped her to get home. There was also a part where they were trapped in a pyramid and to get out they had to give the man who owned the pyramid, a lymeric he couldn't say. I don't know the author or the title so either would help a lot!
