Moonspear being with you,

Orca II wrestled with her sister for a bit before trotting to go and get herself a quick drink. But today it seemed there was something in the water—

She growled at them, but they growled back. Orca scampered backward, confused, but undeterred. She marched back toward the water again, bristled and bigger… but so was her opponent! 

When she showed her teeth, so did they—and Orca growled, forgetting all about her thirst.
