all right people another one of these questions

so i got a 4ft Long x 18 inches wide x 18 inches tall. what should i put in it? i like the jungle theme my lil bro has for his cresti so i want to do a large jungle theme for this cage any suggestions?

forgot to mention it is a marty made so the glass sliding doors

I'm about to set up a 4x2x2 bioactive enclosure for some pink tongue skinks. They're arboreal so a jungle theme with lots of branches/plants should work nicely.
