The Pink Shrimp Grendels were a genetic breed created by C-Rex during 2008. Amphibious, they had Classic Grendel heads, Aquanorn bodies along with legs, and Maraquan Grendel tails. They also had a bright pink tint, hence their name.
Unfortunately, the computer that the Pink Shrimp Grendels were stored on suffered from a crash, but it is believed by C-Rex that they are still on the second hard-drive within the computer (the Tutti-Frutti Norns were also rescued from this drive). C-Rex may decide to retrieve them in the near future and release them to the community.
