for the mouse ending--- take the spoon from the bird cage-- get the cauldron starter from behind the box on the bottom shelf-- then take the cheese and put some of the dingleberry jam on it the mouse should then be stuck-- put in the yellow vial and the blue vial, stir and then use it on the mouse-- then put the red vial and the blue vial in, stir then use on the mouse-- then congratulations on getting the mouse ending
