Tiptup Jr.

Tiptup Jr. is, as implied by his name, the son of Tiptup. He is one of Tiptup's twenty children and the only boy, as his other nineteen siblings are all girls.

Banjo-Tooie
In Banjo-Tooie, Tiptup Jr. can be found in Jolly Roger's Lagoon. He is initially still in his egg that, according to Tiptup, was supposed to have hatched 32 weeks before. Because of that, Tiptup asks Kazooie for help. She needs to use the Hatch move in order to hatch the egg. After that, Tiptup Jr. will break out of the egg but fall onto his back, thus being unable to move. Kazooie then needs to use another move, Wing Whack, to flip him over. As a gift for the help, Tiptup gives the duo a Jiggy he found in the sand and goes back to the sea with his newborn son.

Trivia

 * If Tiptup Jr.'s still unhatched egg is hit with a Grenade Egg, Tiptup will ask what the duo is doing and say that "that's no way to open the egg" and that they will blow up "[his] little one in pieces".
