There is always Mouth Man hoodies for the kids.
The creator Ross Valory, an original member of the band Journey, came up with the idea by seeing a kid doing just that- crossing arms while making monster noises. Of course, he didn't look as cool as these kids (or kid? Or twins? Or clones? Confusing). I actually think it is a fun idea for the kids, even for the adults! I can imagine myself wearing the shark one to next year's Halloween party, and looking pretty SHARP (Get it? Ha Ha).
Unfortunately for me, these hoodies only come in child sizes (2T, 4T, 6, 8, 12), and will only set you back $25 dollars with a lifelong supply of headaches (repetitive chomping noises will do that to a person). But look on the the brightside, you don't have to lug toys around for their entertainment, this is a toy! I can just see it now, chomping battles between T-rex and Orca Whale at every doctor's office. Sign me up!
If you want to check out or purchase one of these hoodies, go to mouthman.com. And remember to keep your eyes open, since inspiration for a new product can come from anywhere. Let's keep inventing out there!
Also, on a side note, thank you for posting comments! I enjoy reading them, and it keeps me fueled on to continue writing. Hear Hear to my readers!
