Glaciers probably destroy things faster than Sylvia- she has yet to more than nibble on anything, including the 3 toys she came with that look like they were bought a long time ago, in a galaxy far far away- suffering bleaching from stars the whole trip.

She does enjoy untying knots, though. I rather wish she would... I miss my gerbil's chainsaw prowess- they could demolish a block of wood bigger than themselves in a matter of weeks.
