The Earth Dragon belching out NaturalGas at her foes.
NaturalGas (天然ガス , Tennen gasu?) is a Yellow Enemy Tech used by the Earth Dragon in Chrono Cross. When activated, the Earth Dragon will literally belch out a plume of gas, which inflicts mediocre damage to all foes.
A loud burping sound can be heard emanating from the Earth Dragon. She then proceeds to breathe out the pent-up gas in her body at her foes, engulfing them in a thick yellow mist. Yellow bubbles are observed to form on each foe, which inflict damage upon dissipating.
