Terry

Terry is the boss of Terrydactyland. Despite this gargantuan flying dinosaur's frightening appearance, he is actually a caring father, although he's not afraid to show his wrathful side when he believes someone intends to harm his chicks.

As Banjo climbs the mountain, Terry spots him from his nest at the top and accuses the bear of stealing his precious eggs, spitting down at Banjo to prevent him from climbing up. Once Banjo safely reaches the top, Terry demands his eggs back, which Banjo and Kazooie don't know anything about, but Terry assumes that they're playing dumb, and a battle ensues.

During the battle
Terry flies high above the nest and spits at Banjo from a distance. After a few seconds, Terry will move to get a better vantage point, leaving himself open to egg fire. After he's taken some damage, Terry will deploy several Mucoids, globs of mucus with a life of their own, onto the field which will proceed to attack Banjo while Terry flies off for a short rest. Dispatch the Mucoids to get a honeycomb and Terry will return, starting the spitting/flying cycle again. Repeat until he's defeated.

After the battle
Only after Terry has been knocked down does Banjo convince the grieving parent that he had nothing to do with his missing eggs, and offers to help Terry get them back. Thankful, Terry gives him a Jiggy in advance and activates a Flight Pad for Kazooie to use. There are four eggs in all: one on a plateau in the lake, one in the Oogle Boogle cave, one inside a crevice in the Unga Bunga cave, and one in a high-up alcove inside the mountain interior where Chompasaurus lives. The eggs cannot be carried, but Kazooie can use the Hatch ability she learns inside the Unga Bunga cave so that the newly born chicks can fly back to their father on their own. One of the chicks, however, is so heavy upon hatching that is must be carried to the top by Banjo using the Taxi Pack. This weighty teradon is always the last one to hatch. Once all four chicks have returned safely, Terry will give the pair another Jiggy.

Trivia
Terri
 * According to Zombie King Jingaling, Terry's wife left him shortly before the events of Banjo-Tooie.
 * Terry is one of many characters in portraits in Banjoland.
 * Terry is also voiced by Frank Welker except he sounds like an actual, mature, nest-living pterosaur.
 * Unlike Terry, however, all of Terry's babies do not speak and not have voice actors.
 * If Banjo and Kazooie did not help Terry then he and his babies would be completely extinct which adds the question why do they say that when there is other Pterosaurs flying around below the mountain.
