We celebrate this legend every February 2nd on Groundhog Day. But how much do you know about these cute little rodents? Did you know that they make tunnels called Burrows that get up to 20 meters long? And did you know that each burrow is for something special? They have a burrow to sleep, a burrow to hibernate, a burrow to have baby groundhogs, and even a bathroom burrow! There’s also a fun tongue twister associated with the groundhog. The groundhog is also known as the Woodchuck (it has a lot of other nicknames, too). The famous tongue-twister is: How much wood would a woodchuck chuck If a woodchuck could chuck wood? A woodchuck would chuck all the wood he could If a woodchuck could chuck wood. Let’s have a contest! How fast can you say it? Do you celebrate Groundhog Day where you live?
