The house elf, feeling helpless and vulnerable lay patiently on the ground unable to support an upright posture, its swollen legs outstretched, it's belly round.

Even through its swollen ears, the voices around it were indecipherable as the Hogwarts representatives watched and waited to see if success had been achieved...

... and they had been.

Slowly, but surely, the house elf's skin started to deflate as the draft took effect. One ear, then the next, it's nose, it's lips and eventually, it was right again.

The house elf showed its gratitude by waving at the girls, wiggling its ears and nose, grinning brightly and squealing many thank yous.

Hogwarts' representatives, had been successful.
