The Cute Pink Go Egg Incubator
This is not a toy, although it certainly looks like one. It's a computer-controlled incubator that will let you hatch three eggs at a time. Not sure who would have only three fertile eggs at a time, but here it is. It turns eggs automatically and has an "optional setting for rare bird types." (Go Egg Incubator, and hatch me an...emu!)
Thanks to Accidental Smallholder for this.
Oh, and Roni, you were right. Freeway signs. The holes are where the reflectors go. Leave it to a graphic designer to recognize where letters come from.
