Waaayyyyy ahead of you!! I already have inflatable helium Panda's ready for the NEC. The idea was to attach them to each Panda but no reason they can't be "adapted" to have an eye patch if someone's creative - don't look at me though, I'll end up popping the things if you let me loose on them!!
They arrived today (flat obviously) and are quite big - about 26" I think so will be quite obvious floating around
This any use...? :idea:
