Flea? is a fake boss of sorts in Chrono Trigger that appears in the Fiendlord's Keep in 600 AD. It's meant to fool the player into thinking that it's really Flea and then attack it, upon which point it will use the counter "MP Buster" (Which completely drains the MP of the attacker) and then die. Afterwards, the real Flea will appear. Although Flea? is visually the same as a Juggler, the player is still fooled into thinking that it is a boss, since Jugglers have not been encountered by the player yet. It should also be noted that it is much weaker than a Juggler.
