Raindeer

Raindeer: noun. A species of deer known to only emerge from their cave burrows during rain or thunderstorm. It has been reported that during particularly powerful storms, raindeer come out into meadows and perform a ritualistic dance, which then extends the duration of the storm for an additional 47 seconds. Interestingly raindeer do not come out during typhoons, hurricanes or tornadoes and it is not known why that is.
