Original Description:

“Day 28: Draw a pony rising to the occasion/Draw a pony taking the bull by the horns.
More likely it’s take the Ziphius by the fins!
Anyway, continuing on from Lilly and Icy’s adventure, they are spotted by the Ziphius, which gives chase. The beast proves too fast for them, so Icy (foolishly) tries to get the drop on the Ziphius before it can catch Lilly. It’s not one of her brightest ideas, as trying to wrestle a creature the size of an orca and has the temperament of a dragon is an easy way to get torn to shreds. But this distraction proves vital as it gives both Lilly and Icy the time they need to make their escape!”
