What is the difference...Puff, Bobble, Popcorn stitches??!!

I don't know about you but sometimes I get confused between the popcorn, puff, and bobble stitches. What is the difference? Do you know?  

I did a little research and this is what I found.


Popcorn Stitch by Lion Brand:

Popcorn St (multiple of 3 sts)

Foundation Row: Work 2 dc in 3rd ch from hook, *sk 2 ch, (sc, 2 dc) in next ch; rep from * across,
ending with sk 2 ch, 1 sc in last ch.
Row 1: Ch 2, turn. Work 2 dc in first sc, *sk 2 dc, (sc, 2 dc) in next sc; rep from * across, ending with
1 sc in top of turning ch.  Rep Row 1 for Popcorn st.

Puff Stitch by Vickie Howell:

Puff: Puff stitch—Yarn over, insert hook in indicated stitch and draw up a loop(3 loops on hook), [yarn over, insert hook in same stitch and draw up a loop] 3
times (9 loops on hook), yarn over and draw through first 8 loops on hook, yarn
over and draw through remaining 2 loops on hook.

Bobble Stitch by Moogly:

Bobble stitches are worked from the “wrong side” – meaning they pop out away from you as you work. They are worked much like a dc dec, but all into the same stitch. To dc5tog, work 5 dc all into the same stitch, leaving the last loop unworked on the hook each time. When you’ve got 6 loops on the hook, yarn over and pull through all 6 sts. Work tightly here, and as soon as you make the next (sc) st, the bobble should pop right out on the other side of your work!
