S4·E11 Cheery Spherey Day / Diary Daze / Rock-a-bye Billie

The Polies invite the Bevels over to celebrate a holiday that reminds them that all shapes are important; Olie has to write down his weekend activities in a diary for a school project, however when he spends all his time thinking up fun activities to put into his diary, he misses out on the real weekend fun; It's the annual Polie/Bevel talent show but Billy can't think of any talents that he has. Olie, however, overhears Billy singing a lullaby to Binky, and points out something Billy has been taking for granted, that he can sing Binky to sleep.
