Zygons play the worst pranks on each other.

 

If you haven’t seen videos of dead dancing squid circulate on the internet, you’re missing out on the weirdest dinner experience around. If you put soy sauce on a squid, even if it is long dead, the salt will react with the muscle cells (even if dead) causing them to contract, which makes for a pretty silly sight of a very wiggly dead dancing squid.

I feel like Zygons would do this to each other all the time
