Jumbo had tantrums. He would try to damage the Elephant House at night. He may have been frightened and angry because Scotty went home every night. He was only calm during the day when Scotty was nearby or when he carried children around the zoo in his "howdah". Jumbo's behavior only made Bartlett more sure that he must find another home for the elephant. Years after Jumbo's death, zoologists studied casts of the elephant's teeth. They discovered that his molars were erupting abnormally and probably causing him pain. This was likely the reason for Jumbo's tantrums.
