I didn't mention the King, Queen, and Big Daddy because they weren't confirmed to me to be in the finale, they were supposed to be staged in the beginning of the attraction but their placement wasn't consistent, nor made sense, so they were placed in the finale for the Mardi Gras celebration that takes place at the end of the attraction.
And as for the rest of the critter figures that the PR team keeps mentioning with every update, the critters are the focus point of this attraction, and they aren't advanced but that's not to say that's a bad thing, it allows the team to fill in the area with a lot more figures of the quality that you see for the fish in the Little Mermaid attraction in MK and DCA. The 17 new figures are all the human cast with a few of the characters having up to 2 and even 3 figures spread throughout the attraction, just wanted to clarify that.
