Action figures of "snail guys" from space that had an outer shell of armor you could remove (think: the looney toons/super hero line of toys from mcdonalds). Stood about 4 inches tall. Also came with a rubber "shell" that you could turn inside out to make it pop in the air, or shoot their ammunition at the bad guys. They also came with a little parasite buddy that could be launched from the shell. I'm pretty sure each character was named after an American president.
