Answer: Probably not, unless Frigimon somehow managed to destroy it herself. Which would be nice, but fairly unlikely, and Terra didn't rely on happy coincidences.

Carefully Dorumon pops up over the broken ice, small enough to have survived it intact. "I'm not sure I can get to it with all of this!" A glance is sent Chika's way - but she knows to hide, and Dorumon's own partner.. apparently does not, given Terra immediately tackles the pile of ice and stone, working on shoving it out of the way. Either they killed the frigimon, or they... got the gear out or something, and buried under ice that's not going to work.

Dracmon's more than happy to leave Mojiyamon to Aquilamon .. it SEEMED as if the bird was going to handle the new fuzzy snowy monster, and she was more concerned about the fact that her Chosen is busy trying to dig out a hostile digimon. As it seemed Mojiyamon was aiming at Chika, it's just a matter of making sure she's not on that same trajectory. "Get away from there! Let us handle it! The other one knows to go hide, so GO HIDE!!"
