Don't be afraid to go for eggs with a Pteradon.. A Pteradon with 1200 to 2200 stam can out run a wyvern after the nerf using the sprint speed and the barrell roll ability on them. Common misconseption is that you can't use them anymore after nerf.
I got a level 150 lightning egg and I was so excited to hatch the egg...that when I went to put the egg down I accidentally ate it instead. :( ps4 users: R2 ISN'T GONNA DROP THE EGG YOU'RE GONNA EAT IT LIKE ANY OTHER EGG. REMEMBER THIS. LOGIC BEFORE EXCITMENT.
