“Ook?”
“Yeah, you know, someone to share the bananas of life with. A comfort in troubled times.” Nobby stared wistfully into the middle-distance.

As if called by a psychic connection, the pitter-patter of hundreds of feet could be heard as the Luggage trundled up beside the Librarian. The lid opened to reveal dozens of bananas in varying states of ripeness
“Ook!” the Librarian exclaimed, patting the Luggage amicably on the lid
“True enough,” said the voice near the ground, accompanied by furious scratching. “I could go for a sausage myself. Or even something from Dibbler.” A tail wagged hopefully in the direction of the Luggage.
