Pineapple is a character from All Hail King Julien. He is the leader of Frank-ri-la and a close friend of King Julien.
History with the Macy's Parade
Pineapple made his Parade debut in the 2017 run of the then-newly re-branded Universal's Holiday Parade Featuring Macy's. The balloon features Pineapple, with a Christmas gift tag declaring that it is a present for King Julien -- from King Julien himself.
The balloon is one of two balloons in the Madagascar unit of the Parade, with the other balloon being Rico's Tropical Blimp. He also appears alongside a sereis of three floats, and an array of Madagascar-inspired costumed dancers. The balloon continues to appear in the Holiday Parade as of January 2020.
