All of this.
For my babies I use the white plastic containers that Hormel Complete meals come in. Cheap office lunch becomes a baby snake hide, just run the container through the dishwasher to clean it and then cut an access hole with heavy-duty scissors.
You can find leafy plastic plants that are inexpensive at craft stores like Michaels. Just make sure there are no closed loops or sharp points that could hurt your snake. Lay them right on top of the substrate so your snake can hide under them.
In the future stay out of the big box stores.
