Blocking your way to the boss...

Acting as the Sub-boss of Stage 1, the Wurtoulge (ウートゥルギ Wuutourugi) is a heavily equipped ground unit with two different attacks: Using its twin spread cannons until the top gets destroyed, revealing a new weapon, more spread patterns, but using large red bullets, but they can be dodged easily.

If the Wurtoulge is destroyed when the large bullets are being fired, they will become  instanly Bonus Items, this only works when you destroy the unit with your shots, if you capture an incoming Esbarel and toss it you will lose the bonus items since the bullets will be destroyed by the aircaft.
