[Crazy Jetty]

Some interesting stuff. The Mouser multipack seems like it finally gets it right (Lots of tiny ones instead of one giant wind-up one the same size as the normal figures).

The Ratking is a surprise, as are the Mousers, Spiderbytes, and Cockroach. And I really like the name Newtralizer.

Maybe Splinter 2, and Shredder 2 are Playmates listening to the complaints and doing something about it. Conversely, I still need to pick them (the originals) up... but now I sorta wanna wait to see if any picks come up soon.

"Ninjas Don & Leo," and "Ninjas Mike & Raph" intrigue me.
I have two guesses... They're probably young versions, hence being sold as twopacks.
That's what I put my money on. But the second guess is that they're dressed as ninjas, and come with swappable heads and weapons, simular to GLC Low/Maash, and Medphyl/Naut Ki Loi.
