After being carefully harvested from the milky crests of frozen Arctic Ocean waves, ice cream must be eaten quickly or it will try to migrate back to the North Pole. Capture fleeting pleasure with today's Groupon: for $3, you get $6 worth of soft-serve ice cream at Moo LaLa in Batavia.

Moo LaLa twirls icy peaks of 95% fat-free, soft-serve ice cream to form elaborate sundaes, parfaits, and sky-high cones. The Rocky Top ($3.58) piles strata upon substrata of spanish peanuts, hot fudge, and glacial sweetness to create an accurate cross-section model of a mountaintop sugar mine. Dessert designers bake fresh triple-chocolate brownies for the rich brownie-a-la-moo'd sundae ($3.58) and whip up spiced waffle-cone shells for a taco impersonator stuffed with pecans, caramel, and ice cream ($2.68). Moo LaLa's soft serve, flavored with either chocolate or real vanilla extract, gleams with cold symmetry in swirls (small $3.35, regular $3.86, big $4.51) that, in a pinch, can be used to propose to a loved one. Meanwhile, mix-ins ranging from cookie dough and Oreos to strawberry and pineapple stud creamy expanses with treasure troves of flavor.
