PokeAdvent: Day 6, “Baked Goods”
#??? | Cinnataur | Normal | The Cinnamon Bun PokemonThis Pokemon is loved by all due to his sweet scent and delicious taste. Yes, you heard me, delicious taste. Cinnataurs, with their Yeast ability, grow back every time a bite is taken out of them. Of course they don’t have this ability until they are happy with you.
PokeAdvent: Day 5, “Those Creepy Elf-on-a-Shelf Things”
#??? | ??? | Dark | The Ornament Pokemon
#??? | ??? | Dark | The Stocking Pokemon
These pokemon like to hang around people’s houses. People, however, do not like them around there. You’ll see the occasional trainer with one of these guys. It’s rare.
PokeAdvent: Day 4, “Northern Lights”
#??? | Auroracadabra | Ice/Fire | The Northern Lights Pokemon
Found in icy areas, they attract pokemon with an array of colorful lights, which are thousands of degrees hot. Due to pokemon attacks not harming humans, however, people gather around to see the spectacles of Auroracadabras.
PokeAdvent: Day 3, “A Cool Physics Concept” - “Time Stops at the Speed of Light”
#??? | ??? | Psychic/Steel | The Speed of Light Pokemon
#??? | ??? | Psychic/Steel | The Speed of Light Pokemon
As someone who’s taking physics, I find no concept cool, but I digress. These Pokemon only appear in daytime, you can not even battle with them at night. But they are extremely powerful, as they slow the enemy pokemon so much, it’s like they’re freezing time.
(((These are loosely based off previous fakemon I’ve drawn way back when)))
The Pokemon Advent Calendar Challenge: Day 2, “ Strange Cuisine”
#???, Sushinsect | Bug | Rice Carry Pokémon
(Based on bug sushi)
Sushinsect carry balls of rice around with them, as it’a mainly what they live off of. How they get this rice is unknown completely, but sometimes they have been known to raid food venues to find some. They are an invasive species in places like Kanto (which is why Spearow were introduced, to drive them out), but in this region, they get along with humans just fine, some keeping them as pets. (And keeping them as battle companions, of course.)
