Suddenly the scratching stopped. For a few minutes they didn't hear a thing. Not even their own breaths.
Sarah, still a bit frightened, decided she had to ask what 'they' are now, or never. She struggled to get the words out, but out they came,

"What are they?", she asked in a whisper so soft, not even a bat could've heard what she said.
"Who or what are 'they'?",she asked again, a bit louder this time.

"Dire wolves", replied her science teacher dreadfully.

She understood the word 'wolves' but what does 'dire' mean? Is it a scientific name?

"What does 'dire' mean?"

"It means fearful, in other words :fearful wolves."

"What?!", she exclaimed loudly. But was immediately silenced by Medusa.
"How many are there?",she asked in a whisper, not wanting to be silenced again. 'I would also like to know what's going on', she though.

"About 3 or 4... maybe more." He replied. Eyes wide with fear.

There came another horrific growl, some sniffing and then scratches on the  door again.
Everyone tightened again.

' How  did this happen ?!', she wondered. 'Billy, is the best science nerd we have. He'll never mess any experiment up.'
