Lickitung will need to be male, and know the moves Power Whip and Curse. It can't learn Curse in Generation IV, unsure about onward games though.
You will need a Female Bulbasaur Evolution (I know, it has to be female. Hold your tears) and put them together in the daycare.
Hopefully, the offspring should be a Bulbasaur with Power Whip (and Curse if you're not using Gen IV)
Good Luck. :)
