Vacation again with Grandma in the Garden
I liked best to jump around on my bubble
Now that's a weird one again 
. The thing in the picture that looks like a giant sausage was made from rubber and filled with air. You could sit on it and jump around similar to a Space Hopper, but it was much larger and had no handles.
Actually this thing wasn't made as a toy at all. It was (and maybe is?) used to close gas pipelines when doing repair work. I think friends of my parents gave it to me.
I remember that my mum wasn't too happy about it because it was quite stressful to our lawn .
