Luigi, Yoshi and P2 go soaring through Yoshi Star Galaxy to collect a Green Star in 1 minute 1.10 seconds [IGT, 3666 frames].

The spring bonk strat was found by Qr1pt1k, and is 0.3s faster than just long jumping up and onto the Magikoopa.

For the infinite flutter, I tried emulating and optimising Jerome's instant triple bounce off the fruit (youtu.be/FduJb1he_Qs?t=26), but it was frustrating trying to angle Yoshi correctly with the flutter.
I eventually managed to get it, but 8 frames of lag are lost getting grabbed by the Smeech, so there's improvement to be made there. For some reason, I actually needed to get grabbed by the Smeech to bounce off the fruit in that way. Trying the same angle and P2 freezing the Smeech ended up with no bounce at all.

After the flutter, I jumped out of the ground pound and spun up to the sign, and from here was able to long jump with a slight rightwards strain to barely land on the next ledge.
Backflip spin was faster than long jump wallkick spin by 5 frames, and by landing on the edge of the spring, I was able to backflip off it which would have saved time if finishing this planet without Yoshi was faster.
Because that route is not faster (see below), and because the Yoshi egg isn't active until just as I land on it, the spring backflip isn't faster nor is it slower than backwards spring jumping.
It is also because of the egg's late spawn that P2 couldn't break it to save time. You can only go as fast as Yoshi eggs respawn.

For the ending route, I first tried going without Yoshi through the launch star (which is a faster way to the launch star) and climbing up to a Yoshi egg near the first moving platform. The route continued with a couple of Z flutters (infinite flutters) out of the first flower swing to the second (the moving platform doesn't move as early as the Yoshi route), landing on the second moving platform and jumping to the next flower swing to do some swings up to the star.
This ended with a 1:01.53.

I then tested taking Yoshi through the launch star, doing a sideflip with flutters up to the first flower swing, which in retrospect had suboptimal execution. The elevator was in a better spot to get a momentum-boosted sideflip up to the flower swing, and then I crouched to get lower in the air to bounce off the Octogoomba.
This - plus a quick spin at peak bounce height - helped to grab the next flower swing much earlier than the no Yoshi route had, resulting in 0.43s of timesave overall. That's just comparing a much more optimised no Yoshi against a slightly sloppy Yoshi route, so it can be a bigger timesave.

Taking 4 swings to the star is 0.3s faster than any alternative routes, such as taking 2 swings and fluttering up to the last swing.

With further optimisation, I expect this to reach sub 1 minute.
