Historical Grow A Colony Update 5.5 notes for the Snake Creature, Snake Raid, archived 2.5% chance, current 599 Robux Pass, odds, and open questions now.
The archived Update 5.5 description added the Snake Creature and Snake Raid, with a 2.5% chance per completed Raid. Roblox lists a 599 Robux Snake (Perm) Pass in the September 9 API check. Update 6 is current and does not reconfirm the old rate or a roll per wave.
