Find your puff a medium box and decorate it, if you would like to, then put blankets or washcloths in the box. Then put random squishy or comfortable things inside the box and put your puff in. If it dislikes the decorations, redecorate it. If it still dislikes the decorations repeat the last step and if it still dislikes the box, get a new one. The puff must be happy with their box because he or she will be in it a lot.
