Tunguska Event is the 5th stage of Stories of Legend sub-chapter 43, Area 22. It is considered a hard stage due to a Spacefish Jones taking out your cats from a distance while Star Pengs and buffed Li'l Bun Buns are pushing towards your base.
At the beginning of the stage, the boss, Spacefish Jones, and a Star Peng are spawned. Roughly 30 seconds later, another Star Peng spawns. From here on out, Star Pengs spawn at 50-second intervals. About 50 seconds later, a buffed Li'l Bun Bun spawns. One Li'l Bun Bun spawns every 65 seconds after one Li'l Bun Bun spawns.
You can use the same strategy in the previous stage in this level.
- In real life, the Tunguska event was a large explosion that occurred near the Stony Tunguska River in Yeniseysk Governorate, Russia, on the morning of 30 June 1908 and is the largest impact event on Earth in recorded history.
