Overview:It's Earth Day today! Hooray! To celebrate, Nature Cat, Squeeks, Daisy and Hal go on a nature hike over to Butterfly Hills. But they don't get too far because they keep running into plastic bags blowing in the wind. Upon closer inspection, they see these plastic bags come from a local supermarket, so Nature Cat calls for a change in Earth Day plans. Now they will celebrate Earth Day by alerting the supermarket of their plastic bag problem!
