Yabba, Yabba, Yabba is the twelfth episode of the second season.
The episode opens with Mr. Conductor sitting on the information booth making an entry in his diary. He saw three cows grazing in a farm's field on his way back from Doodle Haven, and asks why the cows' milk is white and not green like the grass they eat. Mr. Conductor also asks if fish sleep as he writes the question into his diary. He ends the entry by writing that these are private questions meant only for the diary, and then vanishes.
