Happy hop

An animal on four legs hops for joy: its front end bounces up and down, its tail swings from side to side and its ears go up, happy, round and round.

What it is for

A dog delighted to see you, a cat with a new toy. It is what Happy, Excited, Jump for joy, Bounce and Laugh play on four legs.

The principle it shows: joy bounces the front end

A happy dog does not jump with all four feet: its front end springs up and lands while the back legs stay put, again and again, and the tail swings side to side the whole time (the tail curling round to one side, then the other).

• 0.18 s — torso 14, the body up 8, front legs 25, forearms 30, tail 25 out 45, ears 20, head -10.
• 0.36 s — torso 0, the body up 0, front legs 0, forearms 0, tail 25 out -45, ears 10, head 0.

Try this

1. Take 0.3 s over its first change instead of 0.18 s: a slower happy hop.

   In the program: ramp · over 0.18 → 0.3

2. Turn the body's tilt to 18.2 instead of 14: a bigger happy hop.

   In the program: ramp · to.part:torso 14 → 18.2

How it differs from the others

Play bow asks to play by going down at the front; Startle goes up at the front once, in fright.
