Chapter 4 of Deltarune was officially released not long ago, and this chapter of the game has been awaited by many players for too long. Many players are very interested in this chapter of the game, and it has a high level of popularity and is currently highly rated. So, where are the hidden bosses in Chapter 4 of Deltarune? The hidden BOSSes of Chapter 4 are also something that players are quite concerned about at the moment, and this is the most frequently asked question at this stage.

In this chapter, there are a total of two hidden BOSSes, the first being the Hammer of Justice, and the other being the Fake Trio. The overall difficulty of triggering these two hidden BOSSes is not particularly high. Their difficulty, as seen from now, is still relatively high, and players need to be careful when dealing with them. This chapter is quite long in terms of flow, and the difficulty is not low, so players need to be well prepared.

Let's first introduce the Hammer of Justice; its trigger is not difficult. In the middle of this chapter, players can obtain the climbing wall item. After obtaining it, we return to the library, then keep climbing up on the far right. Climbing up, you will see a golden piano. After finding it, we also need to look for the music sheets.

In the game, we need to find a total of 3 music sheets. After collecting all of them, we can go play the piano. After playing, wait for a while, and the Hammer of Justice will appear. Players then need to defeat it. The overall trigger event is short and simple.

Next is the Fake Trio. The condition to trigger this trio is that players need to complete Chapter 4. After completing the chapter, load the save, and in front of the gate, you will see a light pillar. Triggering it will take you back to Castle Town. Then enter the TV room in Castle Town, and inside the door on the left is where this trio is located.

The above is an explanation of where the hidden bosses are in Chapter 4 of Deltarune. There is also one thing to note about the Fake Trio. If players do not recruit enough characters in Chapter 3, they will not be able to enter the Fake Trio's room. This is something to pay attention to in Chapter 3.
