Amigurumi T Rex

I just taught myself how to crochet a coupple weeks ago and with Easter right around the corner I thought it would be a great present for my son's Easter basket :) I thought this little T-Rex needed spikes which I made by doing this-
Round 1: 3 sc in a circle
Round 2: Ch 1, 6 SC in loop.
Round 3: (1 SC in next, 2 SC in next) 3 times [9 SC]
Round 4: 1 SC in each SC [9 SC]
Round 5: (1 SC in next 2, 2 SC in next) 3 times [12 SC]
Round 6: 1 SC in each SC [12 SC]
If anyone has any questions just lmk! ♥ Happy crocheting!!
