"ROSE!"
Rose Tyler winced at the thunder in the Doctor's voice. He was really annoyed this time, even more than when she'd saved her father's life in the past and messed up the timeline. Hearing his footsteps pound down the hallway, she hugged her soft, fuzzy armful more closely.
The Doctor burst into the TARDIS control room, his arms also full of soft fuzziness. He did not, however, seem to be taking any pleasure from it.
"They're in the library and the wardrobe room and the swimming pool," he said angrily, dumping his armful which squeaked but landed safely on an already large, fuzzy pile. He brushed impatiently at the fur all over his black leather jacket. "At this rate they're going to take over the entire TARDIS - and I'll never get the hair out of the pool!"
"I… I'm sorry Doctor," she stammered. "I didn't know. The man swore they weren't dangerous. Who would think one single tribble could cause so much trouble?"
