Walkthrough
- 1079. Lets get those fingers moving
- Lemmings: 15, Save: 12, Time: 5:00
- Make the first Lemming a floater. Have the next two mine to the right and left to create a holding area.
- The floater should hit the wall to the right upon landing. Build three bridges upwards to the left from the edge of the steel platform above.
- This long bridge acts as a safety platform. Build up to the small steel ledge jutting from the enormous wall to the right.
- Make the floater a climber. As he heads to the exit, have a Lemming build outwards to the rest of the group.
- Exhaust your supply of climbers to have everyone scale the wall and reach the balloon. - 2080. Something Fishy!
- Lemmings: 50, Save: 49, Time: 5:00
- Set the first entry box's release rate to 99, making all Lemmings floaters. Save these floaters.
- Rotate the level to the left to see the other entry box and lower its release rate to around 25.
- The second group of Lemmings will walk up a stairway. When the first turns around, have him build a bridge from the fourth step from the top, creating twelve steps to the left wall.
- Bash through that wall, then build one bridge to the top of the steel wall on the left.
- Meanwhile, monitor the floater bashing through the stairs below.
- Once the floater is through, have a Lemming build a bridge to the stairway, as the bottom is bashed through.
- At the top, have a Lemming bash through the wall. When he is 3/4 done, have another mine left towards the exit at the tunnel's midpoint.
- The bashing Lemming will hit a switch, opening the door for the balloon. Make him a climber to save him if desired, though not necessary for the 49 saves.
- The required 49 Lemmings will reach the exit. - 3081. T is for Teamwork.
- Lemmings: 2, Save: 2, Time: 10:00
- The Lemming on the right should build one bridge to stall. The Lemming on the left handles the main tasks.
- The Lemming on the left walks across a disappearing floor below a weasel. Build after crossing to hit his head, turn around, and flip a lever.
- This opens the floor the weasel is on and a door to the right. Build across to this door.
- Mine to cut the bridge off early.
- Build up to the switch from the steel ledge. This closes the floor below (not needed).
- Make the Lemming a climber/floater after flipping the switch. He will exit the chamber, drop down, and head for another switch.
- This second switch reverses two doors. Bash through the wall to the left and watch the Lemming go through the portal.
- After the portal, build at the very left edge of the platform. Bridge to the next platform, then build up to the ledge to the right.
- Bridge the gap to the right by hitting the tall steel wall and turning around.
- Build left to the small wall and bash through it.
- Build over a tiny, barely noticeable gap.
- After the bridge, the Lemming goes through a super-speed machine and floats to the ceiling due to an anti-gravity field.
- Wait for him to walk right, then build at the steel wall to turn around.
- Upon returning to the ground, dig twice to reach the metal door above the balloon.
- Build to the right to hit his head on the stairs, and he will enter the balloon.
- Return to the other Lemming.
