1934 Monkey Appears

Level 1934's mission is to break the gift box within 50 turns and then break the ball inside. Additionally, the four monkeys on the right are a hidden threat. They can only be eliminated with items, as expected. What's a good item combination for this? Mirrorball with another item combo!! This time, I combined it with horizontal and vertical missiles and eliminated many of them lol. Here's a screenshot when the last monkey was eliminated. I don't know why its expression is so cute lol
