Donating Dinosaur Track in Animal Crossing
''Hoo, I say! Woo hoo! A fossilized footprint. Looks like some paleontology is afoot! Hoo hoo hoo! But truly, this is quite an earth-shaking find! I've never seen a specimen that can match it in beauty. The distinct three-toed foot tells us that this is the print of a theropod from... perhaps the Jurassic period, eh wot? It's impossible to discern anything more specific, but speculation is free, and a vital part of paleontology. Imagine a terrible carnivore stalking its prey... Its great weight pressing down into the earth... and... voila! History! Hoo, aren't I the blatherer! I beg your pardon, please! I do hope I didn't put you into a comatose state!''
