Make it a bed. You can use a small box and put blankets and a pillow in it, or if you want, you can make it sleep with you in your bed.
If there is a mark or stain on the Beanie Boo, use a slightly damp washcloth, then dampen the Beanie Boo very slightly as you wipe away the stain. You can use a bit of soapy water to spot clean stains, but don’t forget to remove the soap residue with a microfiber cloth dampened with only warm water. Let your Beanie Boo air dry before playing with it again.
However, make sure that you keep your eyes on them at all times; if you lose them, you may never see them again.
