IIRC it completely spells out the joke. The last panel says “type 2 diabetes” or something like that

I didn’t know rumble was such a popular feature. It’s one of the first things I turn off in every game.

But the first two seem plausible!

Hm I guess I did get it, but was wondering if there’s an actual, tragic circumstance that causes birds, frogs, and turtles to pile up lol. Thank you for the in depth explanation!

I don’t think I understand the last 3 panels. Is it intentionally vague, or is it a reference to something?
