Well, Hiccup will worry about it, because he's really not looking to make enemies here. Before he can say anything else though Gomamon pokes his head back out of his shirt, looking quite dazed.

"...Ok, if you EVER do that to me again, you're gonna be sorry, Hiccup. Real...Real sorry!"

And yet, Gomamon doesn't...make much of an effort to pull himself out of Hiccup's shirt either. Actually he appears pretty content to just sit there how he is for the moment, his claws poking out the top, leaving Hiccup quite uncomfortable.
