The Spiked Mine is a throwable weapon that, on impact with the ground, will get stuck and start emiting a team-coloured blink as well as a 'beep' sound, which will be reproduced faster if an enemy moves close to the mine. As of v123 Alpha, spiked mines will no longer be detonated when an ally/the player walks over a mine thrown by the team. On thing to bear in mind is that it kills Shrooms and Birds on contact, making it possible to disable Shroom and Bird spawners.
