Banjo-Tooie
In Banjo-Tooie, when Banjo and Kazooie first reach Terry's Nest, Terry mistakenly thinks they stole his eggs, starting the boss fight. Once he is beaten, Banjo manages to convince they did not actually steal his eggs, even offering to bring them back home. This causes Terry to give them a Jiggy and activates a Flight Pad to aid in their search. Once all four L'il Terrys have returned to the nest, the father rewards the duo with another Jiggy.

It is one of the few exhibits to not feature an Information Point, with the other ones being the giant tree itself, the Cheese Wedge and the underwater statues.
