A Gromit Collective

What is the collective noun for Gromits? A Growl of Gromits? An Invention of Gromits? A Grin of Gromits? What do you think?

I (Annie) was in Bristol again for work today. I spent a happy couple of hours in the evening finding Gromits in the wonderful Gromit Unleashed collection. 14 down, 66 to go!

I (Chris) lead a very hot "hill efforts" run with the club tonight. 20 minutes of continuous looping around a steep incline with the downhill as a recovery jog/walk each loop. Despite the conditions everyone got properly stuck in and we all felt good as a result.
