I don't understand people's confusion
It's been confirmed already by Gilles that Pinnochio is Turbo Granny's power, i don't understand why people are still confused about this and making up theories about hidden powers.
The knights have no way to tell if Okarun is telling the truth or not about not having his powers anymore, they only just met him, they can't just take his word for it, specially when they know he has ID Cosmos which btw is NOT some sort of hidden power, it's simply the willpower to not give up when your own life is in danger, instead they have to target their loved ones, this is mentioned not once but TWICE but people forgot.
This entire arc/operation is happening because the dragon knights are operating under fake/false intel about Okarun still having TG's powers, likely part of CSG's overarching plan, because he realized Okarun did, in fact, not have powers anymore and just backed down.
If the actual Turbo Granny were to show up right now and showcase her powers, EVERYONE in the dragon knights would just gang up on her and start giving chase, completely ignoring Okarun and the others, the only power they are missing to complete Vlad's plan is Pinnochio, they don't even care about Acro Silky or Evil Eye, they were just gonna let him get digested inside a dinosaur.
