The biggest threat during this stage is the Flame Cantor, a dangerous enemy capable of dealing massive AoE damage to all deployed units.
Place Kind Bangboo (Miss Esme) at the center of the field so she can protect your units whenever the boss unleashes its skill.

The strategy of this stage is to always keep a Brave Bangboo (Paperboo) at the exit, so it can tank all the damage from the Dullahan while having the Rapid Bangboo units deal long-range attacks to it.

Immediately upgrade both Excaliboos first before any other units. It will increase their range, allowing them to hit enemies from 2 tiles away. They can also hit enemies over the wall. Then, place Miss Esme to give you AoE healing and Snap to slow down enemies while giving additional damage.

There are two phases for this stage due to the Arlaune that can obliterate an entire area. It's important to have the Avocaboo upgraded at all times to counter this as much as possible.

The only ones you need to keep an eye on are the Arlaune, so it doesn't explode too close to your bangboos. Other than that, the chokehold in the exit should work to neutralize the Dullahan.

The only big threat is the Arlaune due to their ability to explode upon being defeated, so make sure your Avocaboo at the back is fully upgraded!
