Scooby-Doo and the Alien Invaders
Third entry in the Scooby-Doo canon, featuring aliens from outer space.
Tropes
Distaff Counterpart: Though she's technically from outer space, it's noted that Crystal and Shaggy are a LOT alike. The same applies to her dog though she's technically an alien too though she's a more animalistic alien than Scooby. It turns out that like Scooby, she's capable of speech, though it's more coherent.
Statuesque Stunner: Shaggy notes that during his love song about Crystal that she is rather tall. Technically, they're about the same height.
