Jump Sentouin (ジャンプ戦闘員) is an enemy that appears in Tails Adventures.
Bomb Nage Sentouins are among the various ranks of footsoldiers in the Battle Kukku Empire, and as their name would suggest, these troops specialise in jumping with impressive agility. They are first stationed in Polly Mt. 1, where they continuously jog in one spot, leaping high into the air once Tails approaches them. If Tails is close enough, they will jump towards him on the third jump and attempt to stomp him. The uneven terrain of the mountain can make them annoying to avoid them, though they can be easily taken out with any offensive item.
They make a second appearance later on at Lake Crystal, where they will ride downstream on rolling logs, simply to get in the Sea Fox's way. The best way to deal with them in this level is to simply shoot them with the Vulcan Gun. Like many enemies in Tails Adventures, Jump Sentouins have a chance of dropping a Ring when defeated.
