There are six Pokemon that I'm trying to see/catch in order to get the..

Burmy, Combee can be found by smearing Honey on those trees. Rare appearance.

Burmy can be found in the sweet honey trees, yes. Trust me, when I say that the trees are all over the place, THEY'RE ALL OVER THE PLACE!! They're trees that have orange leaves. You need honey, though, to put on those tress to attract the pokemon. This can be bought in Floaroma Town, from the guy in that flower field. Once you put honey on the trees, between 3-10 hours, the tree should be shaking and a pokemon will battle you. Which pokemon will battle you is random, but Burmy can also be found from a bug catcher in Eterna Forest.

Combee is also found in sweet honey trees. They're much rarer than Burmy, though. However, he can found from an aroma lady on route 208.

Drifloon can be found from a trainer in the 5th gym [Hearthome]. I'm guessing you're past that part, though, so he can found on Fridays in front of the Valley Windworks.

Goldeen can be found all over that place, using a good rod, and from a fisherman on route 205.

Unown can only be found at a certain point in the Solaceon Ruins.

Finneon can be found, once again, all over the place using a good rod, and from a swimmer on route 223.

Burmy:Eterna Forest, Bug Catcher
Combee:Route 208(outside Hearthome City), Aroma Lady
Goldeen:Route 205, Fisherman
Unown:Solaceon Cave, (wild)
Finneon:Route 223, Swimmer

You use the Honey on the sweet-smelling trees. Wait a few hours, then a Pokemon should appear.

Heres the easyest Way! Go to www.Cheatplanet.com. And click DS, Pokemon Diamond (or Pearl) click features and Complete Pokedex. It tells You everything you need to know about the Pokemon you want!

I may be wrong but I think I have an answer for one of your pokemon. i believe drifloon only appears on fridays. So on fridays walk in the grass in front of valley windworks and I think you will find him.

On route 222 a fisherman will have a Finneon in his party, In Eterna Forest there will be many bug catchers but one will have a Burmy. On 20b there will be an Aroma Lady and she'll have a Combee, a drifloon can be caught on Fridays at the Valley of Windworks if it's not Friday set you Ds clock to Friday, Goldeen can be seen on Route 205 with a fisherman, and Unown can only be found in the Solaceon Ruins. I hope that answers you question.

Drifloon is at valley wind works on friday. You can see him drifting around.
Finneon is at valley windworks. Use good rod.
Unown is in the cave on the right side of solocean town.
And the trees are yellow trees you can find almost everywhere. I use the honey trees behind floroama town. You need honey though.You get that behind floroma

I dunno where goldeen is.
It would also help if you answered the question by StuckInTheZone. Thats me.
