It's a remarkable carrot, Giok, thanks for posting. (I bet carrot producers love getting more than one carrot from a seed.)

Reindeer, however, eat Reindeer Food. Here's the recipe:

Granulated sugar
Food coloring
Oatmeal (uncooked)

Put some granulated sugar in a bag. Drop in a dot of green food coloring. Stir to coat the sugar. Repeat with red food coloring.
Place some oatmeal in a flat dish. Sprinkle on some red and green sugar. Set out on December 24th next to the cookies for Santa.

I guarantee you that by the morning of December 25th, it will be gone! Such are the nutrition requirements of miniature reindeer flying all night.
