Awesome sauce:

The Enrichment Center reminds you that the Cubli will never threaten to stab you and, in fact, cannot speak.

Warning: Pregnant women, the elderly, and children under 10 should avoid prolonged exposure to cubli.

Caution: cubli may suddenly accelerate to dangerous speeds.

Cubli contains a mechano-liquid core, which, if exposed due to rupture, should not be touched, inhaled, or looked at.

Do not use cubli on concrete.

Discontinue use of cubli if any of the following occurs:

itching
vertigo
dizziness
tingling in extremities
loss of balance or coordination
slurred speech
temporary blindness
profuse sweating
heart palpitations

If cubli begins to smoke, get away immediately. Seek shelter and cover head.

Cubli may stick to certain types of skin.

When not in use, cubli should be returned to its special container and kept under refrigeration. Failure to do so relieves the makers of cubli, Institute for Dynamic Systems and Control, and its parent company, the Swiss National Science Foundation, of any and all liability.

Ingredients of cubli include an unknown glowing substance which fell to Earth, presumably from outer space.
