"Air in the depths"

About half a year ago, during one of his deep down strolls, Blubby happened across a dolphin that was exploring as well! That wasn't really unusual for him, but they looked interesting; they had a birthmark on their head that made it look like they had goggles. They also looked rather low on breath, so Blubby blew out a bubble for them to breathe in. They parted ways after the dolphin had refreshed themselves, and haven't met again since.

Won't Blubby be surprised when he finally sees Lenn again...
