Blue Lion's abandoned bunker

Here's blue lion's bunker, because of the broken door, the lion has been stuck for years into this bunker before someone pulled him out, he was stuck long enough for a giant tree to grow over and die on the bunker, maybe thanks to the lion powers, who knows ? Hided in the mountains, behind a forest, this bunker was a really good hiding place, it was equipped of antennas and vents, but everything's down now except the lion himself. The roof can also be open to get access to the inside of the bunker.
