Hey, Bobby used to do this as well.
My children called it the Penyu Pose (Penyu = Turtle) because it looks like the flippers of a turtle.
Wani says Shamini is too fat to do the Fish now.
In case you're wondering how it came to be called the Fish Pose....actually, I don't know! My children started it when Cow fished around!
I googled and found the yoga Fish Pose, which is nothing near our animals' Fish Pose!
