Hot Oat

Hot Oat is the first plant obtained in Iced Stream in Plants vs. Zombies 2. It is unlocked in Iced Stream - Day 1.

Hot Oat, in Iced Stream, warms all the plants around it in a 3x3 area. Then, it melts the ice tile below it (the gimmick of Iced Stream) after doing so. It is meant to be used to be a cheap sacrifice to keep your plants going.

In Frostbite Caves however, Hot Oat just warms all the plants around it in a 3x3 area before disappearing.

Origins
Hot Oat is based off the Avena sativa, otherwise known as the common oat.

Hot Oat's name refers to two things, Hot, which refers itself to it's warming ability and Oat, the plant Hot Oat is based off of.

Strategies
Hot Oat is vital to your survival in Iced Stream. First of all, it warms up plants, alllowing them to shoot faster and keep those zombies down. It can also be used with Ice Lily and it's first form, where it shoots droplets that solidify the further they are on-screen. Hot Oat+Wintergreen is also a combonation to use, as Hot Oat warms up plants, then melts the ice, killing it, and then Wintergreen can be planted to refreeze that ice, allowing plants to be planted on that tile.

Plant Food Effect
Hot Oat cannot consume Plant Food, as it is a instant-use plant.

Pepper-mint Effect
When boosted with Pepper-mint, makes it warm plants in a 5x5 area rather than a 3x3 one.
