If there's one thing animal behaviorists know about llamas, it's that these four-legged, furry, camel-like creatures absolutely 'love' celebrating Halloween. As evidence, look no further than the All Hallows' Eve llama card shown here. A playful gray llama dons a scary skeletal costume and happily prances along against a bright orange background replete with black spiders and bats and a garrulously grinning jack o' lantern. Anybody receiving one of these somewhat spooky and completely hilarious cards will be swept up in the fun-loving Halloween spirit almost as much as llamas annually are.
