Play Garden 11. Start at the bottom and begin climbing up. After the first Spectra you will a platform with five seeds to the right and another five seeds to its left (Screenshot). Begin gathering pollen, being careful not to hit them. It is acceptable if you cannot activate the further ones; just wait until prowlers appear then begin opening the seeds. More pollen will appear after you do a three seed combo.
