Well, toothpaste isn't really a food. And you shouldn't eat it, being as Fluoride is actually poisonous. (it's a by-product of Aluminum-Refining, and was classified as 'harmful waste' before someone probably got paid to put it in your water) (side note: this was on a food page on Sonic Gear, but I decided to put it onto hygene for Sonic District)

This is (presumably) a 50ml tube of toothpaste with a Sonic the Hedgehog theme. Fortunatly, it tells you it's minty...but is it blue? This is by Search, and is fairly old. It is quite uncommon.

The tube itself is even an interesting component. It's clearly metal with an all over design. However, they've chosen an unexpectedly arty route, making Sonic so large that he becomes nearly abstracted in the wrap around pattern. It's also a nice touch that the tube isn't simply a copy of the box. Someone has clearly taken some good time to design the whole presentation. Good to see! 

Of course, you wondered what the paste itself looked like...well wonder no-longer! Here it is, and it is indeed blue. As seen at left, the tube does wrap all the way around with stock Sonic, & even has a star on the back.
