The phrase "rolls up" can be replaced by a variety of synonyms, depending on the context. These include "curls up," "twists up," "tucks in," "folds up," "coils up," and "bundles up." Each of these terms conveys a similar idea of something compacting or pulling together, often with a circular or spiral motion. For example, a person might "curl up" in bed when they're feeling cozy and relaxed, or "tuck in" the corners of a sheet to make a tight bed. Similarly, a hose might "coil up" neatly when not in use, or a blanket might "bundle up" when being carried.
