Yoohoo the Senegal(Yoohoo and Friends X Sonic the Hedgehog AU)

On a peaceful island that isn't too far from the famous Sonic the Hedgehog's hometown lies a group of Mobians who have made sanctuary there ever since a tribe of Mobians first stepped foot on it a long time ago. There was something that they found while they stayed: a magical spring with beautiful waters. Not much is known about this sacred spring, mostly over the fact that the residents of the island guard the spring with a rumor surrounding it saying that the water from the spring could make you young forever with a few sips, hence the spring's nickname the "Fountain of Youth".

Taking a break from going after Sonic all the time, Doctor Eggman teams up with the mysterious but yet shady figure Big Boss, as well as his alligator minions Oops and Koops, to travel to the island to salvage the mysterious water hoping that one day, the Big Boss could sell and turn the water into cash. To do that, he would need Eggman's help with his Badniks to destroy and drive all of the Mobians off of the island while Oops and Koops come up with schemes of their own. In the midst of it all is where Yoohoo the Senegal and his friends work together to stop the villainous duo from taking their spring water, as well as destroying their home, while going on their own wacky adventures!
