Wooper will evolve at level 32.
Sinister Woods on floors 8 thru 10
If there is an egg, ask the old lady's husband outside the daycare, he has the egg. But make sure you have an open slot in your party, or else you can't take the egg. You should be able to take our Pikachu and Wooper then.
Wooper is water and ground type, so a grass type should do it.
In Pokemon Diamond & Pearl, Wooper evolves into Quagsire at level 20.
