1988 First release?
 

Well ninjaturtles.com lists the party wagon as being part of the 1988 first release, I was always under the impression that it was released in 1989. I know for a fact the technodrome isn't a 1988 toy either, but ninjaturtles.com has that listed under 1988 too.

So my question is this, which figures and vehicles were released in the first wave in 1988, and if certain toys were released in 1988 but not as first release please list those as well.

This is what I know for sure

1988
Leonardo
Michaelangelo
Raphael
Donatello
Splinter
Shredder
Rocksteady
Bebop
Foot Soldier
April O'Neil

but what are the vehicles?

Vehicles in '88.....

Cheapskate.
Turtle Trooper.
Knucklehead.
Turtleblimp.

Yeah, the ten figures and the four vehicles are all I know of

I was pretty sure that the knucklehead was 89 or 90, not 88. Are you 100% positive?

The party wagon is always listed as '89 on eBay, so I figured it wasn't a true 88 vehicle. I think you're right about the trooper, I have the Knucklhead but I dunno where it is so I can't check on that one, but I think you're right with it as well. Lemme check my Blimp but I thought that was '89/'90 as well.
