- For the level before the v1.8 update, see Sky City - Day 1 (Pre-1.8).
(Crazy Dave and Penny appear)
Crazy Dave: Wow! Where is this? It feels like we're flying!
Penny: The data shows that we are at an altitude of 11045 meters.
Penny: I think you can find something special here.
Crazy Dave: But I'm afraid of heights! I know, maybe there is nothing special in a place so empty.
(Crazy Dave and Penny leave)
Crazy Dave: Only flying plants can be planted on the sky.
Crazy Dave: When the ship is under attack, it gets damaged. When the ship gets destroyed, you lose the level. Try to protect the ship.
- The gimmick of Sky City is completely different from other worlds. This change may give players difficulty. Zombies also come in quickly in Sky City. Rotobaga is given to the player, which can be used to defeat early zombies.
- Zombies in Hard Mode can be Level 3, which can be difficult to deal with. The Rotobaga provided will do almost nothing unless upgraded. A better choice would be Aspiragus (the game levels it up for you as you get stars.)
