Four reindeer trotted into the San Francisco Zoo this past Saturday and have proceeded to blow kids' minds wide open. According to the Chronicle, children were gasping at the sight of them, astonished they didn't have wings to fly with Santa's sleigh on Christmas Eve.

Holly, Velvet, Peppermint and Belle, who have been munching on grass and locking their horns in play are visiting the Zoo for the holidays. They're just kids themselves--each only about 18 months old.
