They make push-button and squeeze toys that cycle through multiple pre-programmed sounds/messages when pushed or squoze.
They sell push-button and squeeze-activated sound boxes that can be user-programmed with a single message.
I cannot, for the life of me, find a place that sells the cycling multi-sound units that can be programmed. I know they have to be out there somewhere, it's the INTERNET, I'm just utterly failing at finding them because illness and 14-hour workdays have reduced my mind to tapioca.
Halp? It'd be nice to have the resources ready for after the Project From Hell is finally over and I get finished with two overdue business sites for friends.
