Reed and Harper are swimming around Virgin Islands National Park, and they want to share with you everything they've learned about mangroves, natural filtration, and the different types of turtles found on the island. For a one-time purchase, read about their adventures, spot the difference between Harper's two sketches, color the postcard, and put the sticker somewhere you can show off your love for the Virgin Islands! 

Includes one double-sided letter, one activity sheet, one postcard, and one sticker.
