How they work and why they are here: Bomb Car - explodes when it stops moving after it starts moving and it can't stop or it will be destroyed Drill Sign - the drill activates when it is placed on the ground, and after it starts digging, you can't see the words in the sign through the ground. Exploding Dirt - It explodes when you step on it, but the ground and exploding dirt is not damaged. Molten Water Bucket - It's a bucket. You don't activate a bucket. The water in the bucket will just evaporate because it is too hot.
