Yahoomer
From Tardis Wiki, the free Doctor Who reference
Yahoomer was one of the aliens imprisoned on Justice Prime. He resembled an orange woolly mammoth with four trunks. He helped foil the Blathereen family's plan to use the Justicia system as a massive flame-thrower. (PROSE: The Monsters Inside)
