Unicorns are always happy and fun.
They make perfect role models.
Unicorns are 100% trustworthy. You never need to fear or doubt anything a unicorn says.
But that can't be said of some other creatures. Be very leery of fake unicorns. Certain unscrupulous characters will attempt to pass themselves off as the genuine article.
But a simple test will reveal the truth. Unicorns never have tuna breath.
Be safe out there, my friends.
