Depending on your view of Lovecraftian elephants, one could argue that the cuttlephant is nicer than the taranturaptor. I imagine that on the surface this creature would look strange, while underwater it would be quite disturbing, especially as it deftly makes its way through the water.
The mashup marathon will continue with another monster in one hour's time!
This swimming elephant has a slightly elongated head and several tentacles surrounding its trunk.

Trumpet (Ex) Once every 1d4 rounds as a swift action, a cuttlephant can sound a highly disconcerting set of notes that dazes all creatures within 30 feet (the range extends to 60 feet underwater) that fail a DC 13 Will save. This is a mind-affecting, sonic effect, and the save DC is Charisma-based.
Many creators of weird monsters desire something as effective on land as in water, and cuttlephants are no exception. Combining the sheer power of elephants with the camouflage ability of cuttlefish, cuttlephants also possess a strange ability to daze their foes with a series of otherworldly notes, as befits their appearance. Despite their ungainly appearance, cuttlephants are extraordinary swimmers and can keep pace with (or exceed the pace of) most non-native underwater creatures.
