Shimohara, Georgette and Hikari are out on patrol when they find the whole lake near the base has frozen over!  It's an ice Neuroi!  They engage the enemy, but it's too cold, and freezes their units solid.  The Neuroi then proceeds to freeze the entire base!  With no one else able to launch, it's up to the three of them to take out this frozen foe.

¿Pero dónde hay combustible?
Pero ¿dónde hay combustible?
Sauf qu’on n’a pas de mazout…
Ma dove troviamo il combustibile?
Mas onde encontraremos combustível?
