Right near the beginning of the game, you'll find 2 areas with tons of chickens that respawn in time. Just keep bouncing between these 2 areas killing chickens until the trophy pops! You can see how many you've done by using the Book O'Stats'N'Stuff in your inventory if you really need.

He can be found at Camp Orqawanga in the very back. Walk up to him and initiate conversation to start the fight. Finish him off and after he blows his final annoying note, the trophy will pop.

At the start of the game, run up to the first outhouse you see and press to activate it, than let an enemy kill you so that you respawn at that outhouse and the trophy will pop shortly there after.

The three queen greems can be found in these locations.

1. Greem Camp near Greem Lake
2. Zombie Greem Camp in the Haunted Forest
3. Greem Camp near Turtle Lake

Use the mating whistle given to you by the exterminator in Pluckmuckel. Once you've killed a queen and collected her "sack" at one of these locations, go back to the same exterminator to get another whistle.

There is a person in the game names "Spelunker" who is normally outside of certain caves throughout the map. He will give you quests where you have to go into a cave for him to retrieve something. You need to complete his missions and the trophy will pop after the 6th one is completed. Also, by checking your map screen, if you are near any spelunker location and have yet to explore it, it will be shown as red ! in a world bubble on the map

While traveling through the game, you'll encounter people who will give you quests to do. Some will have only one while others will have multiples so keep talking to them after you finish a quest for them in order to make sure they don't have any others. Once you finish your 50th side quest, the trophy will pop. These are the quests that are listed under "Unimportant Things I Need To Do" in your Quest Log. You can see how many you've done by using the Book O'Stats'N'Stuff in your inventory.

This will mostlikely come over the course of playing. If by the end of the game the trophy has yet to pop, than just run around the different areas killing enemies untill it does. After your 2500th enemy killed, the trophy will pop. You can see how many you've killed by using the Book O'Stats'N'Stuff in your inventory.

This will probably come over the course of playing. Just make sure to keep drinking potions when you need a health kick quickly or at random if you are just going to complete the 50 needed for the trophy. Potions can be bought, obtained from chests, given after the completion of a side quest or dropped by enemies after you kill them. After your 50th one taken, the trophy will pop.

This will come over the course of playing, but you can keep circling around and kill enemies if you wish to grind it out faster. Once you reach level 20, the trophy will pop.

While playing, press on the controller to goto the pause menu, then select Settings, than Global Game Settings. Near the bottom are 2 slide bars with skulls on them labeled good & evil. Slide the skull on the good bar all the way to the right and the one on the evil all the way to the left. The trophy will pop shortly there after.
