A Tale From Gizmo

I dip, dip, dive in
Kick my legs five feet
I pull, pull down there
Push my feet one inch
Liquid glass cream
Soaking up stones and shells
Punched by bright light
Iris out, shark I see
Slip in, cave one
Cavern two, door three
Three, a small crowd
Real strange company
Twist left, lunge right
Smell sweet, cocoa leaf
Brown hot pebbles
Soft, then real clingy
