Get Squiggling

Series about Squiglet, a monster who populates his plain white world using a magic crayon. Squiglet draws an elephant called Eleanor, who makes the loudest trumpet sound in the jungle. The other jungle creatures are annoyed that they never get a moment's peace with Eleanor honking all the time. Struggling to find a way to keep her trunk quiet, Squiglet gets a clue from his Squiggle Pad - they should form a band and join in with Eleanor's trumpeting.
