Waterbears!

The Waterbear, or Tardigrade, is a miniature animal which

— moves smoothly like a bear, has legs, claws, eyes, skin and muscles
— has the colour and surface texture of one of those sweet bear gums loved by children
— doesn't need to carry along a knife and fork as it has two in-built knives
— can revert to an "instant coffee"-dry state which resists storage in
liquid nitrogen, contact with mineral acids, organic solvents, radioactive radiation and boiling water. After this kind of brute "scientific" scrutiny the miraculous creature is still able to return to normal life—it needs only a small droplet of water!
