Doug the Glowbug is loosely based on the Mediterranean Pale Glow-bug (Nyctophila reichii). He can come live in your forest for a limited period of time after you rent him from the shop. Everyday he will give you FREE currency just by tapping him. Doug is a busy bug and won’t be in your forest forever, so make sure you visit him as often as you can because you need to tap him each day to collect his glowbucks!
Please note, Doug will expire if you keep him in your storage - it's best to have him out in your forest!
