From Sonic Retro
|Game: Sonic Unleashed
|Affiliation: Eggman Empire
Found only in Mazuri's Entrance Stage and Jungle Joyride Day Act 1, Egg Shackles behave much like the Mega Chopper Badniks from Sonic the Hedgehog 3. If Sonic makes contact with them, they will latch onto him and slowly suck the rings out of him one at a time while also preventing him from jumping very high or using the Sonic Boost. To shake them off, the player must repeatedly Stomp or use the Foot Sweep.
|Don't let its tiny stature and cute movements fool you--these guys will start draining your ring supply as soon as they latch on. Shake 'em off quick, or they'll suck you dry!
