Senator Barca came rushing over the Sand Dune to talk to Peopatra. 'Help, Im being chased by
Grundos. Can I hide here???
'. Peopatra nodded and lifted up the carpet concealing the trapdoor
in the floor of her tent.
All but two of the Grundos chasing Barca were Green, all but two of the Grundos were Purple, and
all but two of the Grundos were Red.
How many Grundos were chasing Barca???
