Carving Through is a decal in Bloons TD Battles, and a skin for BTD6 it looks the same in both games. In BTD Battles it costs 50 medals and in BTD6 it costs 500 Monkey Money. When a Bloon with this decal leaks in BTD Battles a BTD2 lead sound is heard. The sound effect is absent in BTD6,because it is supposed to be a rewarding sound for the person who sent it.
