The Tennessee Valley Federal Credit Union sponsors the Chattanooga Zoo’s porcupine exhibit, which is under construction and is a part of the zoo’s African expansion. The zoo currently has one family of African Cape porcupines. The Prickles family recently welcomed a set of twin brother porcupettes (the official term for baby porcupines). One of the brothers has been named Nickel Prickles by zoo staff, and now, TVFCU is hosting a contest to name the second porcupette.
