#216.5 - Born with a tremendous sweet tooth, Teddiursa are constantly in search of honey, and have even been observed to concoct their own by blending fruits and pollen collected by Beedrill. Their desire to fill up on honey stems from their instinctual need to stock up on calories before hibernating in the winter. Teddiursa grow considerably while hibernating, and though they’re generally good-natured, they are known to be grumpy if their deep sleep is interrupted. Maturing Teddiursa diversify their diet, and spend most of their waking time in search of berries and other food.
