Combinik

The Combinik was a special badnik from the Marble Garden Zone on the Floating Island. It was built from the parts of three different badniks (legs from a Mantis, arms from a Tunnelbot, and parts from an unknown third badnik), and was therefore three times as difficult to beat. It also contained three organic batteries, specifically small birds. It was impervious to Sonic the Hedgehog's Spin Attack, as well as Amy Rose's crossbow. However, it was eventually defeated by being lured into a mud pit, where it was stuck and destroyed, freeing its captive animals.
