Toby also told us there's "only one ending".
Don't take that fucker at face value, ever.
"Busy" could mean he's busy not existing, or busy waiting for Sans to universe jump so he can then do whatever the fuck results in the creation of his brother.
In fact, I'm willing to fucking believe Papyrus only first came into existence in his very first appearance in the Kickstarter Reward Tier video, which fulfills the criteria of "somewhere with grass, but he also doesn't know what the sun is" that the Q&A established in terms of what his life was like before Snowdin.
The same video that Toby privated a few years ago.
