I couldn't complete this challenge in Blue and make my way to the Indigo Plateau without an Army of Puffs, so here are my proud six fighters. I named them alphabetically to keep their order of capture in, well, order. The Puffs are...

Alpha Sing Thunderbolt Mega Kick Body Slam

Beta Sing Body Slam Seismic Toss Reflect

Celia Sing Psychic Body Slam Watergun

Danni Sing Body Slam Ice Beam Bubblebeam

Ellie Sing Body Slam Fire Blast Blizzard

Haelie Psywave Strength Flash Toxic

I originally captured five Jigglypuffs, mainly because I felt that if I had six, I'd always be putting one back in the pc in order to use a different pokemon with the HM move I needed, like Cut. However by the time I reached Vermilion City, I felt a sixth Puff was needed so I took the long way back to Cerulean through Digglett's Cave in order to catch the final member.

The letter "F" was skipped over for Fonze, my Squirtle who helped me get the Bolder Badge in order to reach Mt. Moon. The letter "G" was skipped over in honor of Gutsy Gama. She put up a great fight (for a level 5 anyway,) and would have been the 6th member of this team if I had caught her. But convinced that 5 Puffs would be better, I let her go. I still kinda regret it, as she probably had much better stats than Haelie.

Perhaps you are wondering why I didn't evolve any of my Jigglypuffs. Surely they would have been stronger, or lasted longer in battle, if I had evolved them into Wigglytuffs. The giant rubber rabbits have an insanely high HP, and their defense and attack ain't half-bad either. .....But then I couldn't call this a Puff Army, now could I? It'd have to be "Tuff Army" which just sounds silly. Although such a silly pun is rather amusing. ^^; But I prefer my Puff fighters the way they are.
