OK, here's a quick and easy boy favorite.

2 different color 260's.
1st one
inflate with 2" tail, burp, tie off.
1" bubble, twist, push air through balloon so that it inflates to end. Use the 1" bubble to wrap that balloon around and make a big loop, leaving a long tail out of the loop. This will be the Dino tail. Lock teist the 1" to the main balloon to secure loop.
Fit the large loop over the child's head and fold twist a section in the front to make it fit their head. This should be opposite the tail on the loop and will look like the dino's front legs.
2nd balloon
inflate with 2" tail, burp, tie off.
Use nozzle to wrap around small balloon and tail on first balloon and attach them together.
2" bubble, twist, 1 1/2" fold twist, 2" bubble, twist, 1 1/2", fold twist, 2" bubble, twist, 1 1/2", fold twist, 2" bubble, twist. These are the spines and back of the dino. After last 2" twist attach at that point to the front of the other balloon where you made that fold twist to look like legs.
Use remainder of balloon to make neck and head of dino. Shape tail and head and draw on eyes and mouth.
I hope this is understandable. It always seems more complicated when you write it out!
