Nyarko is usually happy and hyper, but she's caught a cold and is stuck in bed. Nyarko is smitten by Mahiro, who's being a little nicer than usual. It's then that they get a report that an intruder has shown up at the North Pole. They leave Nyarko behind to recover and find that Mi-go was waiting for them...
I'm going to follow them as 
soon as my fever goes down.
Si me baja la fiebre, iré 
enseguida con ustedes.
Si me baja la fiebre, iré corriendo a buscaros.
Vou atrás deles assim que a febre baixar.
