The latest thing to come from Tomy's line of blindbag Gacha type toys are...these "Danglers"! But what are they? They can be keychain charms, cell phone charms, or really any type of hanging decoration. They have a lead loop of tough cord so you can hang them almost anywhere. With on the photo, you can see they're really quite small! That's a Toy Island Giant Talkin' Tails, a Jazwares 3.75 line Tails & the Gacha Tails. Each one is fully 3D and is posed after a piece of the newer 2011 stock art. The figures you'll see with this batch are:

Knuckles, Tails, Eggman!, Shadow & 2 Sonics. (one of which won't stand up) None of their ear-interiors are painted (as seen here) and the Sonics will lack mouths in most cases. Each has a little tough card type logo tag (removable if you want) The package also contains that little folded paper, with anti choke warnings on the back in most languages.
Some of the poses from the art don't translate all that well to 3D (look at Tails' awkward arm behind his back) and their tiny but extended limbs may make them not super durable. Hopefully this sees another line with Rouge/Amy/Metal Sonic/Super Sonic, instead of 2 Sonics, both of which are heavily added to all boxes. (so your chance of a duplicate of him is high, no matter what you do)

These ARE inexpensive, they should be only about 2.99 at Target & Fred Meyer stores. In summer 2012, if you can still find them, a price drop to 1.99. Look for these where you found the previous gacha dispensers for the above figures & racers. Anywhere that retails trading cards / rubberband bracelets may also pick these up. These can have paint flaws, as seen with Knuckles eye-white paint that doesn't go all the way down, or some nose paint on the face.
