After beating the last gym leader she won't give you the badge until the dude behind the gym says your worthy once she give you the badge and the TM Dragon pulse go back to the dragons den and talk to them then you should get it if you don't well you must have not done something wrong (i got it just as i was writing this so i know it works and before you go just go talk to the gym leader and see if you've gotten it) if you have it shell talk about new bark town and how its going to be harder from now on.
There are three men in the Dragon's Den temple. Of course, he is the one in the top middle. If your party is full, then he will not give you a Dratini. Go to the Poke Center and deposit one of your Pokemon and go back. Then he will give you a Dratini. If this doesn't work, you REALLY must've done something wrong. Hope this helped you!
To catch a Metapod in Pokemon SoulSilver (And in Pokemon HeartGold as well), you have to enter the Bug Catching Contest at The National Park on Tuesdays, after you obtain the National Pokedex.
