Zeke and his Mum are cloud watching and talking about breathing when Zeke decides he wants to thank the trees and algae for giving us oxygen. He thanks the tree with a hug, but algae are too small to thank the same way, so Zeke has the idea of fishing rubbish out of the ocean as a way of thanking algae. Mum, Zeke and Ky make some fishing nets and go the tidal creek where Zeke learns that all life in interconnected.
