This may seem like a dumb question but I just want to be sure. Is there any difference between Spirit Halloweens Try Me buttons and the Step Here pad. I ask because this weekend I picked up the Sickening Reaper and Pumpkin Nester. In store, both use the Try Me button. The instructions for the Reaper say you can use the Step Here pad for activation. The Pumpkin Nester has a connector that looks like it would work with the pad, but in the store display its hooked to the Try Me button. The instructions for the Nester say nothing about the Step Here pad. It seems like that is something you would push, so people buy the extra step pad, and the sound activated Nester is annoying, I'd rather the pad. I don't want to try it, and fry it. That would be my luck. Thanks in advance.
