What a really neat bug! At first, I just thought it was a bouncy toy, but when I squeezed it in my hotel room this evening, I flashed back to the 70s. If we'd had these then, I might have never escaped!
Not sure if I can get it through airport security, but I'm traveling a bit on business over the next few weeks so who knows where I'll drop it off? I rarely even know where I'm going myself!
