okay so the Lava Guava Quest is literally the same level but with changed plants and zombies to fit the world.
Severe World Level or whatever quest it is is just a repeat level from an expansion. First was MD Day 36. Hopefully it's not something like... AE Day 34.
Haven't done JM yet but it looks kinda hard.
Pinata Parties giving packets is great (at least for a leveling scrub like me)
And now we get 3x Pinatas by doing one zombie killing challenge is great. No more having to waste a bunch of levels just to get specific zombies.
