Wandering the seabed one day, Blubby came across an interesting sight: An oddly blue gallade, stuck in a water bubble and seemingly trying to get out, stretching the bubble around! "Hblold obln, I'bll geblt yoblu oublt!", he bubbled as he rushed toward them... But, the moment the gallade noticed his fear for them, they quickly shook their head, glubbing that they were fine, and they simply enjoy being in water-filled bubbles.
Blubby quickly calmed down, and wondered what it must be like to be in a water-filled bubble, since the only ones he could make were full of air. The gallade, having introduced themselves as Blade, seemed to be able to tell the dragon was thinking about that, but said they couldn't make another big bubble for him right then. Blubby's face lit up at that. "Yoblu cabln dblo iblt toblo!?" He quickly blew a head-sized bubble to demonstrate. Blade was certainly happy about that as well, and popped their own bubble to surface and catch their breath before returning to help him.
The dragon blew out a bubble he estimated would fit him, and with a push from Blade, he was able to slip inside. Then, Blade swam to its top and poked a finger through the bubble. To Blubby's surprise, the bubble didn't pop; instead, when Blade moved their hand back, there was now a hole in the bubble that water was pouring through! Blade then somehow conjured a water-filled bubble around themselves - Blubby would have to ask how eventually - and the two began playfully stretching their bubbles around.
Some time later, while Blubby was still having fun and not really paying attention, Blade was having trouble holding their breath. It seemed they'd run out their magic, and couldn't pop their bubble on their own any more... Surely Blubby will notice in time?
