Been a while since I saw it - don't know if I'll remember everything...
In a seemingly bone-chilling day, with temperatures at rock-bottom, TR are practically suffering from frostbite. They then see a Froslass, which is thus beckoning them to follow her. Not a good sign, as since Froslass is a ghost, having one such ghost beckon you is a sign that death is coming. They follow it, being the dipsticks that they are, & I'm expecting them to be dead from frostbite.
Just as soon as that's done, we then head to Ash & his gang, who are also caught in the said blizzard, & like TR, they are ill-prepared for times such as this. However, they are smarter, if only slightly, because they actually try to find a shelter with a means of getting a fire set up. Unfortunately for them, nature conspires against them by sliding some snow on top of their fire, & for the double whammy, that same Froslass that supposedly lured TR to their deaths is now beckoning them to follow her. This time, however, a nice & cozy cabin awaits them; Froslass leads them inside, & supposedly shelters them from the blizzard; she even makes them warm food - a perfect setup if I ever saw one. Once Dawn's Piplup gets in the tub, everything goes to hell, as it turns into a block of ice, & the cabin turns into an ice cave. However, instead of condeming them to an icy death, Froslass took Piplup hostage, & to top that off, she did the same thing to TR's Meowth. Turns out, she wants her child Snorunt back in her hands, which happened to wander off into the wild blue yonder. Being the pure-hearted people that they are, they decide to help her out.
As the search commences, they happen to bump into TR, but there's no fighting & carrying on this time, as they both have much bigger fish to fry. THey soon join forces for the time being, & soon, they find the Snorunt; they also found more - a Glalie, but this one has evil intentions. It just so seems to be that this one in particular belongs to a poacher, who wants that Snorunt for his own gain. Everyone gets in his way, but he's not amused; he sends Glalie to them; they try to fight back, but its endless flurry of attacks seem to be too much. Combine that with the fact that Glalie can fire off a Hyper Beam (I'd like calling it a "Special Beam Cannon") & still be able to fight back immediately afterward gives me the hunking suspicion that the poacher's Glalie is haxxor'd. Just as soon as all hope is lost, Froslass joins the fray on Ash's side, & with their combined strength, they pummel him & Glalie into submission. They then cage them in his own cage & leave him to die from frostbite.
Froslass is reunited with her child, they get their Pokemon back, & all is well. After they leave, the temperature starts to climb to the point that the snow starts melting - that means no frostbite for the poacher, but he's still going nowhere...
Looks like my memory is still as sharp as ever! *snickers*
