I hate sidekicks in Disney movies
Frozen was alright but I hated Olaf so much, he was not funny and was just annoying. When I saw some previews of Moana with the rooster Hei Hei, I thought wow another dumb pointless sidekick that will get in the way of the story, but...
Hei Hei was indeed stupid but I absolutely loved him, he doesn't even have to say a word and he still ended up being hilarious.
Even the water was funnier than Olaf
Olaf can learn from it
