Lego MOCS: Hobgoblin

Legend has it that there is a mischievous entity roaming Okoto, aligning neither to good or evil, but to its own whims. Those that run into it recall that they were asked a riddle. If they answer right, they are given a small trinket. If wrong, they are bombarded with the power of its Staff of Puzzlement and later wake to find that they're elsewhere or that their valuables have been stolen. No one can agree on the origin of this creature or whether it even exists.
