Is fg!Ranboo able to fit more than one person in his stomach at a time? If so I can imagine Tubbo freaking out about Wilbur and going "open up" and demanding he be swallowed too lol.
He can fit maybe three humans since it’s really only meant for one giant baby (if he had one)
So yep when Ranboo tells Tubbo that Wilbur doesn’t want to leave he demands to be let in too. Wilbur is very annoyed though that Tubbo is so loud and has so many questions because he just wanted to relax
