How do you get lileep in platinum?

Answer 1

the only way to get lileep in this game is by going underground digging into a wall and then, if your lucky,you find a root fossil.you go to the treasure part and say put in bag.go to oreburgh city in the museum and talk to the scientist guy. he'll ask you for the fossil and give it to him(have an empty space in your party) and walk outside.go right back in and he'll give you lileep

p.s. if you want cradily, lileep evolves at level 40
