So it's another anniversary and I dusted off my old party poppers to go celebrate.... and discovered that the older model poppers can't be used when moving anymore. The new ones can, but not the fiery or explosive poppers.
They all "kind of" work when moving, in my experience, now. The previous ones only offer a brief burst of whichever effect before cutting off, so that's definitely been cut down. The new one will fire out many balloons of whichever type when standing still but only bursts out one when moving.
In any case, they're definitely not fun when running anymore. :/
But now we can leave balloons everywhere. I am sure that won't get annoying.
