The Goggle Wearing Gannet.

Gertrude and Gerhardt get the injured Gary back to his parents' nest. The doctor arrives, and Gary tries to explain what happened.

Gary's Da attempts to teach Gary, Gertrude and Gerhardt the basics for diving safely. He has to change his plans and does three demonstration dives instead. Chicks being chicks though only have a short attention span.

Gary, Gertrude and Gerhardt have their second diving lesson with Gary's Da. All goes to plan and the three chicks successfully complete their first dive and catch their own sprat, but before Gary completes his dive, he needs to take a close up look at where the sprats actually are.

Gary and his Da are walking on the beach, when Gary spots a shard of glass in the sand. Disobeying his father he picks it up and starts to look through it, he is amazed at what he sees. Later Gary's Da spots a starling wearing a funny looking contraption over his eyes.

Gary's Da goes in search of the the peaked cap, scarf wearing starling he spotted the previous day. He finds the staring, who goes by the name of Col. Starling, at a local watering hole and asks him about the contraption he wears over his eyes. Col. Starling agrees to help Gary's Da purchase a similar pair of goggles from a Mr. Maggie, a very dodgy magpie.

A goggle wearing Gary excitedly tells his parents about what he can now see, just before he dives and catches some food for them. Later he meets Gertrude who has some very interesting information about Gary's Da. Gertrude and Gary disagree on what to do with this information.
