Glowing Pocket Firefly
The bug is all wooden and initially, I couldn't work out how it is supposed to work with no buttons or batteries. We charged ours under a light as we haven't had much sunlight when we initially got it. That night, when the lights were off, wow! The tail part of the bug really glowed! It is currently used to motivate my 5 year old to sleep (lights out time) as he loves looking at the glowing bug. He sometimes takes it under his blanket too make it glow even more.
