For "flip flop", flip each hand forwards up by your head.
For "wig wag", flip a hand backward and forward.
For "zig" step onto your right foot and for "zag" step onto your left foot.
I have a puppy, his name is Wags,
He eats so much his tummy sags.
His ears flip flop and his tail wig-wags
And when he walks he goes zig-zag!
