Macdonalds Styrofoam, an incredibly literate squirrel, all the more incredible due to the fact that very few squirrels were even aware that they had literature, let alone an alphabet.
A life-long confidant to Ratty Sock, Macdonalds Styrofoam became press secretary to Ratty Sock after he'd changed his name to Ratatat-tat and gained political power through his vast army, eventually becoming President of the Squirrels. During a raid on GreedTech in 2014, Macdonalds Styrofoam and Ratatat-tat both fell into a huge vat of immortality serum, and subsequently Styrofoam became the longest lived squirrel in his race's history.
Macdonalds Styrofoam died during the Air Wars at the end of the year 3032, the last of his race.
