By what are Stephano and Trinculo distracted when they approach Prospero's cell? What is Caliban's Reaction?

They are distracted by the sound of music......Caliban tricks them by leading them into a bunch of throny briars and a murky pond.

oops...... they are also distracted by the fine garments placed by Prospero's cell.

stephano and trinculo both were distracted by the shiny and glossy (only cause their clothes looked dirty)garments that were hanging in a rope.

whereas caliban was in a hurry to murder prospero first cause if prospero wakes up he will turn every one of them to different shapes and torcher them by pinching every inch of their body
