I have seen several sporrans made from plush toys. One I saw was the Cookie Monster.
There was also a sporran here that was made by a rugby fan. If I remember correctly, he took an ordinary sporran and added the team logo on the flat and swapped the tassels and put little rugby ball keychains. It was well done. The more capable of this forum could get you that link.
I think there is also someone in the NorCal Rabble (or affliliated to) that has a crazy sporran.


Then there is the rubber chicken sporran........ but I wont go there.....
