Cyndaquil knows Lava Plume. I only had Wigglytuff, Diglett, Sunflora and a few others left to beat because of Lava Plume. I'll do missions to get useful items and more money and then head back there. I had Sleep and Stun Seeds when I battled Primal Dialga. The hero, Shinx, is LV 35 or so and the partner, Cyndaquil, is LV 34 or so.
Lava Plume! <3 I was Cyndaquil in Darkness--that move saved me so many times in Monster Houses and similar situations when I was swarmed with enemies. Rollout may help too--it hits several times in one turn and can add up to deal massive damage. Cyndaquil learns it at level 40.
Shinx learns the priceless Discharge at level 41; if you'd like to, you could train a little more to learn it. It proves to be extremely useful.
If you have any of the Pokemon-specific items, you might want to carry them in your Treasure Bag too--boosting your stats and giving yourself extra bonuses. (Ex: Glare Sash for the Shinx family heals your HP when you're hit by a Ground-type attack.)
I'd personally recommend raising your levels a bit; the higher your level and stats are, the greater the chance that you'll be able to endure attacks from enemy Pokemon... plus you'll be able to deal more damage to them. You might want to aim for learning Discharge, if you plan to make that attack part of your moveset.
Good luck! Pass that graduation test with flying colors, okay?

Question: I was looking through the song list for the Sky Jukebox and noticed that at the very end, I have several
??? (still locked?) tunes. I know I haven't played any of the Special Episodes--is completing them what unlocks these songs? (I've beaten the game--evolved--Guildmaster Rank. Is there something I haven't done?)
