Unicorns! Unicorns are the most legendary and magical imaginary horsey things in all of ancient mythology!Rainbows! Rainbows are the most scintillating collection of colors ever to appear across the sky due to refraction of sunlight on atmospheric moisture!Combinations! Combinations are the most recursively literal way to have two separate things bond together into one (it's kind of the definition)! What you see here is a combination of a rainbow and a Unicorn! A combination of mythology and science! A combination of cuddles and snuggles! Unicorns plus Rainbows. It just works.
