The best thing to do now would be to paint on yellow elmers glue and cover it with either dry dirt, or pea moss for Home Depot, let it dry..Shake off excess and then using white elmers glue mixed with water at a 50/50 ratio..Put in a spray bottle and mist the base and using a paint brush at the same time and dab the glue make sure its wet...Let dry. now you have a earth covered base..Now you can go back and hot glue leaves,sticks and rocks...You can also dab glue and but down leaves.. and you can push in your habitat materials..You can use sheet moss and glue it down, you can also use the Spray adhesive to lock down your habitat...
What is going on this base?

?Good luck. Bases By Rick...
