The Tittifers are CGI enhanced birds with their own unique songs . There are four small blue Tittifers (Shaft-tailed Finches), three larger pink ones (European hoopoes), two big green ones (White-cheeked Turacos) and one multicoloured toucan (either Channel-billed Toucan or White-throated Toucan) with a huge purple beak. They sing usually between segments, and when they sing together, near the end, it is time to sleep. They were first featured in the episode "Makka Pakka Washes Faces". they all sound like different instruments Piano Whistle Trumpet Saxophone
