you’d think it would make him heavier, what with the new muscle and (perhaps) a denser bone structure.

but what if the bite changed his bone structure to be less dense? more light so he could easily swing himself around, make his footsteps even quieter for stealth, and add to his flexibility.

i just thought it would be funny if

tony goes to help peter up when he falls (like, grab his hand to hoist him off the ground) and completely underestimates how much strength to use and sends the poor kid flying.

Aunt May and Peter are watching a movie with Peter’s head in her lap, she tries to get up to get something to drink & Peter - joking around - holds onto her, not letting her up. May laughs and once again, underestimating how light he is, she jerks herself up and yanks Peter with her - so she stands there with Peter easily clinging to her like a koala. “Peter what the fu-“

(in the end she just easily walks to the kitchen with Peter wrapped around her , giggling the whole way because she still wants her drink and no feather light spider-kid is gonna stop her)

Peter wanting to prank Tony by tackling him - but as he jumps onto his back the man doesn’t even budge, so Peter just awkwardly sits on Tony’s back.

“kid it literally feels like i’m wearing a backpack do you even eat”
