That place, however, is not under a hot iron. Boo on that, I say! Some pieces of the Gabba Gang need a little straightening out and they are 100% acrylic. So here's what you do:
1) With the wrong side of the piece facing you, cover with a clean, cotton towel and smooth down any noticeable bumps - no pins necessary for this. Use a white towel if you think the colors might bleed.
2) Set the steam to high and the temperature no higher than wool and start ironing the piece flat, keeping the iron moving. Use the steam release button if you have one for extra steam. Depending on the size of your piece this should take 30 seconds or less.
3) Remove towel and let piece set for a few seconds. It should now be ready to adorn your plush.
Notes: If you fry your yarn, turn the iron temperature down and make sure you have steam. If you want the blocking to last you can add a stiffener to the piece, but I like a little more fluidity. Mooches ~ OP
