Pushing further in to the waterlogged tunnels, and having to quaff each of our potions of underwater breathing to get past some areas, we enter a fairly spacious cavern. Suspecting that the jig is up and the enemy knows we are there, because what sounds like a rather large gong sounds repeatedly right after we enter and we see shapes moving towards us under the water ahead, we prepare for battle.
Half-way through the fight with a few waves of Sahaugin that came upon us, the Mage looks around for the celestial creature that he summoned to help us in battle, and when he cannot see it asks, 'What happened to my porpoise?'
We had to remind him that it had it had sunk to the depths of the pool, probably wondering why its master, who had summoned it from another plane to aid him as best it could, a goal the porpoise took to heart and tried its very best to achieve, had cast Colour Spray at point-blank range directly in to its tearful eyes, laughing as he had done so.
Oh, perhaps some Sahaugin had been caught in the effect as well, but the true motive behind the spell was clear. What a wicked little Halfling we travel with.
