THANKS for all your comments guys - it's a pleasure to make em, if you enjoy playing it's a bonus
Here's a spoiler for each bit, pick out what you need and thanks for playing
First Bit
1. Peegue goes right, pushes barrel in water, barrel gen starts.
2. Peegue goes thru yellow tp, then back thru it again to tramp into Loof's enclosure.
3. Fill puddle and place wooden box on yellow button.
4. One character goes thru white TP and stands still, 2nd character goes thru and stands still, first character steps down out of the way, 2nd character pushes barrel in water, first character pushes barrel north thru white TP, now you have a spare item to cover red AND yellow buttons, 2nd character hoys barrel right thru white TP (it explodes, you don't need it).
5. Next step is to block bottom of white TP with the goobs and the other side by someone standing there allowing the other character to reach the pink button
Second Bit
1. One character remains on pink button whilst the other tramps into the next section (landing on green button).
2. First move the solitary prism a couple of squares to the left, you only have one shot with the cannon. Access via bridge tile on lowest part of the ice slide.
3. Fetch cannon from the that little ice slide room and shoot the top row of 4 prisms, the others should all smash too.
4. Put cannon on green button
Third Bit
1. Bottom right room, move both steel boxes one square (left and right) so they are adjacent to the ice and set red boulder moving - it will go back and forth.
2. I think you can start either side, I start with the right hand steel box. as boulder is rolling back to the left, dash round and move the right hand steel box level with the puddle. As boulder comes back and passes, step down, boulder will stop where you were standing.
3. Now push steel box in the water and set boulder rolling again.
4. Get ready to run behind the other steel box and push it back towards the right to block red boulder level with the puddle.
5. Push boulder in the puddle to complete bridge and then place remaining steel box at the bottom of the ice slide.
Fourth Bit
1. Jump sequence for top left bonus coins/conveyor area. Stand where the row of 4 prisms were and prepare to tramp to the right.
Go R D D U and finally L as character goes thru the red TP.
Fifth Bit
1. Switch to the other character that was on the pink button all this time. First collect the rainbow coins in that room where all the prisms were (and white timer switch).
2. Avoiding cannon fire, collect rainbow coin in conveyor switch room and then push the cannon into this room. The prism will smash and this action delievers a transporter to the stranded charater top left.
3. The stranded character can now head to the main section on the transporter, doubling back at one stage for some bonus coins round the island - it doesn't complicate the ride.
Sixth Bit
1. Meanwhile, the lower long puddle should now be filling up with boulders, the last one will activate the white timer switch.
2. Now bridge is complete, character can walk round to the pink goop and tramp bit.
3. Tramp north, then coming back, push the pink goop one square south and the ice cube over the wall to destroy the cannon.
4. Follow the ice cube and walk over the timer switch and stand on the round conveyor button - the other charater can now step off the transporter
Last Sequence
1. The character which has just stepped off the transporter must put the steel box on the dark blue button before leaving that room and head for the exit.
2. Before tramping north into the last corridot home, throw pink goop over the wall onto the pink button.
3. Now both characters can exit

I really enjoyed the method to get the bonus and one rainbow coins in the upper left corner of course you do have to plan ahead for that one, If you don't, 
Well you all will see, Finally everything began to fall into place, Every room a fine puzzle to solve and there is an order to follow, Well done. 
Cheers Matey! I look forward to another 400, Carry on... 
- but only for the beginning part (kept getting Peegue barrelled) and for the iceslide/tramp bit (had no idea I had to tramp through the red TP).
