Round 5[edit]
The fifth round contains eighteen platforms, four regular doors (all but one of which have knobs on both sides), two power doors, seven double-strength trampolines, and three Mewkies (the third being the new, fatter, sunglasses-wearing one); catching four cats in a microwave emitted by a power door is also worth 2000 points (Nyamco will once again double it), and when the fatter Mewky trips over the mice can use the time to walk past him harmlessly. However, if the fatter Mewky should manage to fully pick himself back up when either mouse is in the process of trying to walk past him, he will kill him.
Round 6[edit]
The sixth round contains seventeen platforms, five regular doors (two of which have knobs on both sides), one power door (which again has a knob on both sides), seven double-strength trampolines, and three Mewkies; the mice will also receive an extra life at 60000 points unless it has been disabled.
Round 7[edit]
The seventh round contains nineteen platforms, four regular doors (two of which have knobs on both sides), two power doors (both of which have knobs on both sides), eight double-strength trampolines and three Mewkies; after clearing this round, the game will announce the second bonus round with the text "BONUS ROUND. STING 
S IN TIME.". As with the first bonus round it contains ten red balloons and one randomly-placed Nyamco balloon - and the mice will have thirty seconds to collect all eleven balloons between them (but some trampolines must again be broken through to get some of them).
Round 8[edit]
The eighth round contains thirty-one regular trampolines; after either mouse has collected the fourth red balloon, they must both take the left path (and after either mouse has broken the trampoline over the sixth red balloon and collected it, along with the seventh one, they must both take the right path, on which they must break a second trampoline). The dimmed images of the Nyamco balloon at the top of the map again show where it may be placed, but if you accidentally take either, or both, of the wrong paths and have to go back, it might not be possible to finish the round before the time runs out.
Once either mouse has collected the Nyamco balloon, the stars in the background shall glow; the text "EARNINGS" will then be displayed at the top of the screen as the balloons both players collected are displayed under their mice (they shall receive 200 points for every red balloon they collected and 2000 points for the Nyamco balloon). If Mappy (or Mapiko) collected all eleven of the balloons in a one-player game he will also receive a "PERFECT" bonus of 10000 points - however, in a two-player game, the mouse who collected the Nyamco balloon shall receive a "WIN" bonus of the same value.
