Zookeeper (The Didus Expedition)
From Tardis Wiki, the free Doctor Who reference
A zookeeper was in charge of a zoo on an Earth-like planet. He greeted the First Doctor, John and Gillian when they arrived while a bush baby perched on his shoulder. He tried to show them his didus, but when he got to its cage he found that it had escaped. The Doctor and his grandchildren volunteered to find the didus, and the zookeeper gave them a cage and a scanner to help them track it down. They returned with the didus, and the zookeeper showed them his newest exhibit, a pterodactyl. (COMIC: The Didus Expedition)
