the world's worst oreo

Absentmindedly Tyrian drug a stick through the thick goopy tar. In conversation with Jupiter, who had experience with the stuff, Tashi had mentioned offhandedly that it could be used to join things together. He wasn't sure his nephew had picked up on that, but it had certainly piqued Tyrian's interest. His current go-to method for joining things was lashing, which was effective in most cases but not always practical. So he was curious about this tar stuff.

Tyrian flopped down beside a bubbling pit - careful to avoid the edge - and began to use the stick he was holding as a spatula of sorts to smear tar across the tops of nearby rocks. Each rock got a different amount of tar and then he began to top each rock with another rock. After awhile he'd see if any of the tar sandwiches showed promise of sticking together.
