This pair of plushes looks especially soft.
The Sonic is probably from 1992, making it one of the earliest plushes available to collect. Tails is likely from 1993. Both use a very soft looking fuzzy cloth for the body, and have small hands. Tails has stuffed 'dreadlocks' type of thing for his hair. The Sonic is about average (great for such an early piece) however Tails has a fattish face and rather large body, due to the makers trying to stuff every detail of him.
