A Kucurbium is a small, black, pumpkin shaped alien that deals massive damage over time especially if there is a swarm. They are somewhat rare and can only be found in the last level of the Level Invasion Gate and in the Kappa Gate.
They can take any where from 5-10 minutes to destroy, depending on how many players are assisting you. Be aware of swarms of Kucurbium that protect a Boss Kucurbium. They attack as one - typically, when a Boss Kucurbium spawns in, it will select a single player and target them until they are destroyed. The Boss Kucurbium and the other Kucurbium all begin to attack at once, causing destruction in a maximum of 5 hits.
Note: Any Alien's rewards in the Level Invasion Gate are split between any players who attacked it, so you will not get the full rewards.
It has been confirmed by Administrators that it's name comes from the scientific name for pumpkin (Scientific Name: Cucurbita maxima. Family: Cucurbitaceae).
Kucurbiums only shoot at it's primary attacker when its at Critical Health.
When killing a Kucurbium (or a Boss Kurcurbium) and having the rectile red on it, should give you a random 10 hour booster. However, this is near impossible to achieve, merely luck, due to all of the players it requires to take down.
The Insta-shield on the Boss Kucurbium will not go away until all the Kucurbium around it are destroyed.
