Quest 16 needs exactly 34 placements
The quest asks for three challenges with exactly 34 units placed. High-rarity caps make that impossible if you bring your normal team.
Common units place 6 times, except Common Gary, who places 4. Uncommon units place 5.
- Equip Patrick, Sandy, SpongeBob, and Squidward. That is 4 commons times 6 placements, which is 24.
- Equip two uncommon units, such as a non-Gary green unit. Barnacle Man and Peanut Guy are the examples. That is 2 times 5, which is 10.
- 24 plus 10 is 34.
- Leave Common Gary out. Using him drops the total to 32 or 33 and the objective cannot be hit.
- Those commons will not clear a hard modifier alone. Bring a partner whose towers do the damage while you place all 34.
Divine door after that
The locked door in the Prestige Cave needs a crafted Mysterious Key.
- Farm three key fragments. Each is a 5% drop, rotating through Middle Ages raid, Camp Coral, and Goo Lagoon raid.
- Craft the key and open the door.
- Pearl then asks for a music disc, a 3% drop from Krusty Krab stage 10, and a crown from Tower of Karate floor 100.
- Collect the Boys Who Cry members from their map drops, including Rock Bottom 10 and Mrs. Puff's Boating School.
- Place them with the Director in front, then the yellow-haired member, the blue member, and the orange-haired member.
- The portal opens to the Divine Castle. Divine crafting and Boys Who Cry, listed at 245 million base damage, are behind that step.
Boys Who Cry band members cannot be put in the trade window. You have to earn them.
