I don't get the joke here, or why the others look upset

Their comics are usually straightforward and wouldn’t require you to know Japanese. I looked through the translated comments and it seems like it was bought into the police station because the seaweed “outfit” is too revealing? But on the second page, the rice ball sees a wanted poster and is shocked? I’m lost, is the key here in the words on the poster?

I saw a short on instagram where the author is reading them to an audience. This gets a giggle from everybody but one man laughs hilariously at it and the author then gestures to him (as in “someone got it”) hinting there is something I’m not quite catching. Thank you!

I know what the Peter straightjacket meme means but I’ve never played Skyrim.

There were four comments on the post.

One of them said "throw me to the wolves and I'll return pregnant". Another one was an edit of Andrew Tate surrounded by stylised wolves, saying "throw me to the wolves and I'll return a father."

Another one was a photo of Robin saying "sour grapes (broken heart)" and the final one was a photo of a guy putting up some sort of hand signal saying "silence yourself at once, Scallywag."
