u can always use cheat engine to get any pokemon u want, even legendarys and non available ones. just take a pokemon which evolves fairly soon, search for his pokedex id x 2 +1, so if it has pokedex id 100 it would be 201, then evolve it and search for that id with the same method. then change the ids/numbers you get as results and change the number to any pokemon u want .
For togepi it would be 351 i guess
