Re: hundred thousander trophy
well i never noticed the time running out any quicker, but now that you mention it i think it does..
i would imagine that it's the more spectra you have on that particular garden and not all the gardens combined.
i did this trophy… it took about an hour or two i think.
the place to do it is indeed garden 3 or 4… whatever one has the big hook shaped plant in the middle of the garden. this is also the garden that first has that particular enemy that split into 5 pieces. you need to go to the hook shaped plant. wait until a lot of prowlers are around and then hit the 5 piece prowler enemy with the spin attack. then very quickly swoop around and collect as many prowlers as you can. if you do it fast enough you can get all 5 pieces of the enemy and then continue to get all the other prowlers around you. when your string begins to run out, you should jump into the air and try to get as many more.
with each additional prowlers, ups your combo, and also give out A LOT more pollen for you to collect. also, each 5 prowlers you get will give you about 10 little pieces of time, which you need to get in order to achieve this trophy.
you must know where ALL the spectre are in the garden and something i did was to clear the path (open the seeds) to that spectre then leave it to clear the path to rest so that you can go straight to them when you need a spectre (to get all you time bar back if there are no prowlers around).
you will get the trophy automatically when you have collected enough, so don't quit the garden until you have gotten it.
I can't think of any other tips, so I'll just say good luck. 😀
