Please stop making edits attempting to re-organize the narrative roles based off of what the Disney Wiki says. Due to repeated incident for this specific cause I am making a community post to educate on the topic:

1-The Disney Wiki is not a viable source for citation as it is not a primary source. Additionally, their information on this particular franchise is not as up to date, nor thorough.

2- Frank's character is often misconstrued as protagonist due to his framing on the poster and top billing for marketing his actor; top billing does not make your character a protagonist. If you actually watch the movie, it's fairly explicitly clear that the main character is Lily Houghton as she is the character with the key decisions and focus in the plot, it is her journey which the other characters (including Frank) exist within and Frank only becomes an active main character around the third act of the movie, though even then as Lily's love interest.

3- If there are already three central characters of varying levels of importance, then no, the CGI jaguar is not a tritagonist.

Thank-you and Kungaloosh
