This speedrun beats all 6 games on the cartridge in a row.
Little Bird can only go clockwise, so the order of the characters/letters is very important as sometimes you can clear all objectives in one circle and sometimes you have to flutter 3 complete circles.
At first I simply relied on luck and reset the game whenever I felt like I had to do too many movements. It really was among the stupidest of all speedruns. Then I looked into how the Random Number Generator (RNG) of this game worked and employed the waiting strategies you see in this run. The RNG advances every frame on the game selection menu, but is not advanced while in the actual games. This means that if you select game 1 on frame 7 and then select game 2 on frame 3, it is the same as selecting game 1 on frame 4 and then selecting game 2 on frame 6 as the total elapsed time is the same.
The RNG fortunately works in "clumps". There are sets of successive frames that yield the same order of characters/letters, so you only need to hit a specific window of 7-20 frames instead of one specific frame. The characters and the order and direction from which they enter the house DO differ though! This is on one hand annoying as you still have time variation as a left side entrance costs 0.7 seconds more than a right side entrance, but the information does allow you to know on which specific frame you entered and how long exactly you need to delay before selecting the next game. I made a table of all character entrance orders to compare against to know what delay to use before the next game.
Game 6 is unlike the first 5. You can't really win this game, you're only supposed to make as many words as possible and you'll get a celebration whether you make 0 or 15 words. So the best is to just do nothing. The sun descends 1 pixel every 3 seconds, but only if neither Little Bird is fluttering nor Big Bird is speaking at the time. Big Bird will give you instructions at some scripted times, so to keep the sun descending it's best to flutter just before Big Bird will speak.
