*Phew* You finally got all the way down. It’s quite a scroll, huh?
The infinite canvas is a webcomics concept that basically says “since your comics aren’t bounded by a printed page, you can make them whatever size you like.” It hasn’t caught on because, well, people hate to scroll. Most comics keep scrolling to a minimum – maybe a screen or two – and rarely do anything involving horizontal scrolling (because it’s awkward). “Traditional” webcomic artists sometimes poke fun at the artists who promote infinite canvases and the like.
But Mr. Stinky doesn’t know these things. And so, when our friends dig a hole, things happen.
