The Wild Monster Invasion 2 has ended. 
Backyard Monsters: Inferno came right after.

" Something strange is afoot in the Backyard. Armies of never-before-seen Wild Monsters have been spotted near your base, and it looks like they're headed right for you. Expected arrival is December 15th. Start preparing yourself now! "

This invasion is the second large-scale wild monster invasion ever hosted in Backyard Monsters. Similar to Wild Monster Invasion 1, it consist of 30 waves and 2 additional bonus waves of enemy monsters. The Wild Monster Invasion 2 was announced on December 8th, and began on December 15th, 2011. Though this event is now over, the next wave symbol will still be present above the building bar. It is only visible if you just opened your account or if you had just finished killing monsters baited with the Monster Baiter. If you click fast enough, the very last wave of wild monsters you killed will attack you. You can use this method to beat the invasion (though this has only been observed on Facebook). It presented many new monsters, including Spurtz, Zagnoid, and Sabnox that were previously seen in Wild Monster Invasion 1. The new monsters are:

• Balthazar
• Grokus
• King Wormzer
• Malphus
• Valgos

Soon after the Wild Monster Invasion 2 has ended, the new Inferno event was confirmed by Kixeye. It is known that the leader of the Inferno army, Moloch, was the unknown monster named in one of the Wild Monster Invasion 2 annunciations.

The slideshow is showing all the annunciations that appeared during the Wild Monster Invasion 2, including messages, that appear when you finish some waves.

Note: Enraged monsters have boosted movement speed and stats and no health bar listed, and as such cannot be killed. They are invulnerable to tower, champion monster and bunkered monster attacks and will only take damage once the enrage has worn off. Usually, it takes more than 30 seconds for the rage to end. To beat the invasion, one must not use a box yard, otherwise they would get thrashed mercilessly. Instead, spread out yards to gain some advantage of gaining the ability to stall raged attacks, allowing towers to kill them. An alternate way is to fill bunkers with octo-oozes or pokey, which are famous for stalling raged attacks.
