How it works.
- Winds up for 12s after it is put down, then goes off once: when a ground nightmare steps into range, or under one that is already chewing it. The blast does 1,800 damage to everything within 0.9 tiles.
- While it winds up it blocks the lane and can be eaten. A smasher's swing or a boss's stomp can destroy it before it goes off. One use.
- Toughness 300: what nightmares have to chew through to get past it.
The Bedtime Book says, at Lv 1
1,800 damage after winding up for 12s. Toughness 300.
And at Lv 25
4,392 damage after winding up for 6s. Toughness 300.
Every level, 1 to 25.
Upgrading costs coins, once, and lasts for good. Lv 25 costs 114,320 coins in all. The green rows are the levels with a milestone perk.

Lv 1 against Lv 25.
The same scene twice, recorded in the game: on top with the toy at Lv 1, below at Lv 25.
Measured from the recording. Nightmares in a real night have more health the deeper the level (the curve), so times there differ; the ratio is what an upgrade buys. Every toy's comparison

The game's tip
Jack-in-the-Box pops ONCE and is gone. Place it ahead of approaching monsters so it has time to wind up.
