The Egg Ninja Art: Flying Squirrel (エッグ忍法・ムササビちゃん Eggu Ninpō: Musasabi-chan?) is a move that appears in the anime series Sonic X. It is one of the many ninja techniques utilized by E-91 Lady Ninja.
When performing the Egg Ninja Art: Flying Squirrel, Lady Ninja pulls out a parachute-like cloth behind her back (along with a short bushy tail) and uses it to glide through midair like a flying squirrel. While the Ninja Lady only resorted to this technique after her Egg Ninja Art: Kite was destroyed, the Egg Ninja Art: Flying Squirrel seemingly allows greater mobility than the aforementioned technique.
