In this video we will look at the new secret world seed "celebrationmk10" added in Terraria 1.4.2.3: Journey's End and everything you need to know about it. This seed celebrates Terraria's 10th birthday/10 year anniversary/10 years since game release. There are new secret enemies (how to find Golden Slime and Jungle Mimic), rare items can be purchased from the Princess NPC (how to get Slime Staff, Coin Gun etc), small versions of almost all bosses (little bosses) and much more!
