PMD1: I was the only person in my entire town to get even close to completing a 99 floor dungeon. I got to floor 98, and accidentally angered the local Klecleon shopkeeper. He turned me into a teddy bear, causing my partner Sceptile to repeatedly whip me with a vine until I was close to death. Fortunately for me, my bag consisted of only reviver seeds.
20-ish Reviver Seeds later I got past the Klecleon hordes and reached Lugia.
"Cue Boss Battle"
After a long and grueling fight, involving 5 Hydro Pumps, 13 False Swipes and a Leaf Blade, Lugia was on 1HP, I was on 203 and Sceptile was on 72. I had just used the 13th False Swipe, and was moving in for the kill...
But Sceptile got there first, taking Lugia down with a measly A attack.
Needless to say I got really angry and threw my DS at the wall, followed by me covering my bedroom walls with pictures of dead Sceptiles.
