Otters are adorable whatever they are doing, but these otters in Japan are extra cute as they try to decipher this unusual machine called a vacuum cleaner. What is it? It makes a lot of noise, it makes the wind blow funny, and it's coming after us! They swing back and forth between curiosity and trepidation as they try to determine whether the vacuum is a friend or foe. They get closer to see what's going on, but not too close! Meanwhile, I've learned there are several collective nouns for otters. The best is "romp," as in a romp of otters. -via Laughing Squid
