Rhode Island Novelty 097138675828 Pow Bat Inflates (1 dz), May Vary

Before inflating how small are they? like if i rolled and folded could i fit into a large3x2 easter egg?

How many come in a package?

Everyone says they are tiny... what is their approximate length inflated?

Item name says "1 dz" (1 dozen) but description says "includes (1) assorted inflatable pow bat, our choice please". which is it? 1 or 12 for $8.41?
