Gungan energy catapult

Gungan energy catapults, or whizboomas, were mobile weapons that used by the Gungans in the Battle of Grassy Plains against invading Trade Federation droids. The catapults launched large boomas that deactivated the enemy droids.

On a sidenote, the texture of the catapults are just like the Gungan Battle Wagon, leading to the hypothesis that the catapults are organically grown as the Battle Wagons are.
