A hatchery for Easter eggs!
It is an Eggulator. It probably produces 1 egg an hour at the cost of 50 granite 25 gold coins and 1000 marble or some other outrageous cost. Don't need it. No thank you.
I don't care what it does, it is much nicer to look at than a golem.
If something can go wrong, it will.
Name it Egg House, Easter Bunny's House, or Easter Bunny Home
It's a basket of urns of dearly departed BB's.
It's a BOWLING ALLEY, DUH! See the little alleys curving around the sides? This is where you make the bowling eggs to play "Splat! the Raving Rabbids" with. We asked last year for a game of "Splat!" and the developers have come up with just that.
It's Agent McBunny's not-so-secret hideout
