If you're looking for a "put together" activity for Puffin Rock, there are several safe, official ways to download and print puzzles and activity sheets for free.
Netflix (with Subscription): Both seasons and the movie are available on Netflix. While not strictly free, if you already have a subscription, you can download episodes for offline viewing within the app at no extra cost.
Because of its high quality, Puffin Rock is premium content. That means finding a legitimate free download is harder than for older, public-domain cartoons.
Puffin Rock Music! App: This is a freeware creative play app where children can explore and remix music from the series played by the Ulster Orchestra. You can find it on the Apple App Store and Google Play Store.
