How to unlock the Serpentine! achievement in Rare Replay - Definitive Guide
Edit: As BryanRPh has pointed out each spin counts towards the achievement, getting 4-5 spins per level. You should be able to get this in a normal playthrough. This does not require 50 completed levels.
In case you missed it: As with many of the other achievements in Rare Replay, this can be easily boosted by exploiting the game save function. Simply save just before a finish line. Load the save, cross the line spinning and get your achievement progress. Repeat until the bloop.
Rewinding will not have the same results. Make sure to snap your achievements!
At the end of 'race' types of stage and similar, your boat will jump slightly as you cross the finish line and you have the opportunity to spin it by holding left or right on your controller (each completed spin will add 1,000 points to your score) - you'll need to reach a cumulative total of 50 spins for this achievement. This can be done across multiple playthroughs and between reloads, but you cannot use the rewind function for this.
You can make good progress towards this achievement in the course of a standard playthrough, but will probably still be quite short of the required 50 spins. To make up the rest of the 50 spins, get to a race style stage - the first stage will do just fine. Play through the stage as normal until you see the finish line, then create a save immediately before crossing the line, getting up as much speed as possible to maximize the number of spins that you'll be able to complete. After completing the race, load up your save and repeat as necessary until you reach the required total.
