I don't think so? Baymax just squeezes through them. He's vinyl, so he's kind of got some wiggle room there. Not like actual metal, you know? Wait, what is that?

[Explosives? That seems kind of dangerous. And unnecessary. Baymax was kind of bigger with being fully charged and himself again in not being on low battery anymore but Hiro still doesn't think it warrants this drastic a measure.]
