They are amazing! The sour is incorporated into the flavor of the gummy, instead of being a powder on the outside of it. They taste like the fruit they are supposed to, except lip puckeringly sour. They also come in 2 sizes - the gummies in the tiny trick or treaters size packets are a little bit bigger then the eraser on a pencil, but in the 4oz packs, the bats are about 7.6 cm long and 2.5 cm tall, and the wings and body are 2 different flavors.

Sadly, Haribo only puts them out at Halloween.
