Wild Monster Invasion 2!
All monsters appear to be new and so far not hatchable. I have posted below text of what is in each wave and below the waves is a video of each. Some of the earlier videos have multiple waves in one video. From what I have seen from other videos, at least the final attacks are not random, but always come from the same side. For specific information on any of the monsters in the invasion just click on thier names below. Monsters that show "Enraged" come in with the buff equivilent of 10 Million Putty from the Catapult. At this time I have been unable to confirm the meaning of MAX, I would guess that L6 is level 6. If you would like to see details of the yard in the videos click here. I would suggest Gorgo as champion and Octo-ooze in Bunkers as best strategy for any round that contains Balthazar.
Wave 1: 10 Spurtz
Wave 4: 10 Zagnoid, 10 Spurtz, 10 Malphus
Wave 5: 32 Spurtz
Wave 7: 10 Zagnoid, 40 Malphus
Wave 8: 40 Spurtz, 5 Balthazar
Wave 9: 20 Zagnoid, 15 Spurtz, 3 Sabnox, 10 Malphus
Wave 10: 20 Zagnoid, 5 Sabnox, 5 Valgos, 10 Malphus, 5 Balthazar
Wave 11: 20 Valgos, 50 Spurtz - 1 wave attack from 2 sides
Wave 12: 16 Valgos, 36 Zagnoid, 16 Grokus - 2 wave attack from 4 sides
Wave 13: 30 Zagnoid, 6 Sabnox, 20 Spurtz, 20 Malphus, 8 Enraged Balthazar - 3 wave attack from 4 sides
This was more tricky. Gorgo is likely a better choice for battles with Enraged Balthazar.
Wave 14: 14 Sabnox, 20 Grokus - 2 wave attack from 4 sides
Wave 15: 40 Spurtz, 36 Balthazar, 20 Malphus - 3 wave attack from 4 sides
