It's going to be a snake.
It's an apple.
It'll evolve with the apple taking over the reptile. The mid-evo will be a crocodile stuck in an apple, like a cocoon and then the final evolution will be a snake sticking out of the apple; worm out of an apple reference, or snake out of an apple, in a biblical reference since the region is in Spain (Spanish Inquisition reference also). Zodiacfags will also be happy as it will end up being a legless reptile/snake.
And because of this, it will be fire = fire wrym/snake and grass = apple. Similar to Appletun and Flapple, only a snake.
The grass evolutions' themes have always been primitive or reptilian/Old World animals that are quite evolutionarily stagnant; Bulbasaur was a dinosaur, Chikorita a dinosaur, Treeko a gecko, Turtwig a tortoise, Snivy a legless reptile whom are also quite old evolutionarily, Chespin an armadillo, Rowlet an owl, and Grookey an ape. The cat will therefore probably evolve into a sabre tooth tiger or a European direwolf considering it's in Spain.
The water evolutions are the only ones that haven't followed a loose pattern. The hat probably means it will evolve into a sailor or have a nautical theme like Empoleon. Considering Empoleon was more intimidating in nature, they may make him similarly buff, or they may do a full 180 and make the evolution into a slender, sleek swan pirate that evokes the image of Jack Sparrow or a Spanish swordfighter like Zorro.
