Yeah they really were. The bright yellow one especially. They were super cool. I noticed they were stretching their necks way out over the grass to look around and make sure the coast was clear. So when I scared them and they went into their shells, I started to mimic their behavior by stretching my neck out and looking around. They instantly popped back out of their shells and started looking around with me.
