Mecha-sleigh Elf

Mecha-sleigh Elf is a special zombie encountered in Arena and Piñata Party in Plants vs. Zombies 2 during December winter events.

This zombie's ability can be split into 2 stages.

Stage 1: Upon entering the lawn, Mecha-sleigh flies through the lawn like typical flying zombies with flighty speed from the pull force of Robo-dolphs. When the front Robo-dolph reaches the leftmost column, the Robo-dolphs lifts the Mecha-sleigh up into the sky out of the player's view, before entering the lawn from the rightmost column again 6 seconds later. The cycle repeats.

Each time the Mecha-sleigh passes through the lawn, the Elf drops a gift bomb randomly on one of the 9 tiles on the row. The gift bomb explosion kills any plant or zombie on the tile.

When a Robo-dolph is defeated, only one Robo-dolph remains so the Mecha-sleigh speed drops from flighty (2 tiles per second) to speedy (0.4 tiles per second) which is 5 times slower.

Stage 2: Once the last remaining Robo-dolph is defeated, the Mecha-sleigh can no longer move and will stay right where it is when the last Robo-dolph was defeated.

The Elf in the Mecha-sleigh will proceed to sing Christmas songs, slowing down all plants and zombies in a 3x3 area (50% decrease in attack and movement speed).

Once the Mecha-sleigh is destroyed, 1 gold coin and 5 silver coins are dropped!

Origin
The vehicle is based on Santa Claus's reindeer pulling a sleigh to help Santa Claus deliver gifts to children on Christmas Eve, with "Mecha-sleigh" based of a mechanized version of the sleigh.

"Robo-dolph" is a red-nosed robotic reindeer with its name coming from the word "Robot" and "Rudolph", a red nose reindeer.

Overview
Absorbs a total of 3600 damage per shot, consisting of the Mecha-sleigh (2000 damage) and 2 Robo-dolphs (800 damage each). Each can receive damage separately and simultaneously like PvZ2 Camel Zombies.

Strategies
This zombie's main purpose it to be a tank for the zombies behind, although it leaves the zombies behind during the 6 seconds it takes to come back down after lifting up into the sky.

Weaknesses

 * Plants that do piercing damage, hitting the two Robo-dolphs and the Mecha-sleigh all at once: Bloomerang, Snapdragon, Lightning Reed, Laser Bean, Fume-shroom, Guacodile, Phat Beet, Ghost Pepper, Cactus, Jack O' Lantern, Cold Snapdragon and powered Shadow Peashooter.
 * E.M.Peach temporarily immobilizes the machine.

Tips

 * With 2 Robo-dolphs, the Mecha-sleigh takes 4.5 seconds to travel the entire row and with 1 Robo-dolph, the Mecha-sleigh takes up to 22.5 seconds to travel the entire row.
 * Try to defeat the final Robo-dolph near the rightmost column, since that's where the zombies mainly are and the singing Elf will slow them down.
 * Blover will not blow this zombie off screen. It will only blow this zombie to the rightmost column, the same goes for Hurrikale.
 * Since most instant kills do 1800 damage, using an instant kill on the correct spot will hit both two Robo-dolphs and the Mecha-sleigh, killing the Robo-dolphs instantly and leaving the Mecha-sleigh with only 200 damage of health.

Trivia

 * If somehow the Mecha-sleigh is destroyed before the Robo-dolphs, the Robo-dolphs will be set free and fly up the sky, leaving the lawn altogether.
 * Upon defeat of the Mecha-sleigh, it crumbles into parts (like Mecha-Football Zombie).
