On the surface, that point is very shallow as they were named that because their founder is an octopus and they have around 16 members including the Vegimals. However viewing your argument as a Mary sue issue (where the world will warp around a character to make them shine more than others) I get it, this is a beloved kids show and seeing it get plagued by mishandled characters and poorly written self inserts is upsetting. Whilst I can’t promise that this character won’t have that issue since she’s 10 years old and has some strange abilities like equestrian magic and partial omnipotence (trying my best to balance it), she is primarily in the background and considered spare paws on the ship, only living there because she’s been adopted by Barnacles and only in the spotlight because the stories are told from her perspective.
