I need help with Goose's Warning.

So around... 5 days ago, me and my friends decided to try an idea: I would create a server, and would use DebugSpawns to troll them, as the other five survived. It actually turned out to be fun, and ended pretty well, long story short. I then discovered something: By using "DebugSpawn "beargerwarning_lvl1/2/3/4" or "deerclopswarning_lvl1/2/3/4", i could spawn in the sounds of when those two giants are about to attack. I ended up trolling them PRETTY HARD during Autumn and Winter. xD But then came Spring. First thing i decided: "I'll spawn in Goose's warning to troll them!" The sound that rings out when Goose spawns, pretty much. But then an obstacle hit me: I found out that since it doesn't have "levels", it wasn't "moosewarning_(something)" or just "moosewarning". I'm now pretty stuck. If anyone that knows a lot about these commands, or can find out what i need to type to spawn in Goose's sound when he arrives, please help me! I'll be really grateful!
