The stickyglobes have replaced their ancestor, the purple globes. They have regained their stickyness on their outsides. They have changed to be extremely resistant to all but the most extreme temperatures and weather, and have migrated towards the beaches of both continents.
These odd plants have an intricate life cycle. They start off by floating in the air, like their ancestor the purple globe. As they mature, smaller stickyglobes start to bud off, but instead of falling off, they simply keep growing. these buds do not contain hydrogen, and eventually, the plant will drift down onto the ground.
An interesting thing to note is that if they hit salt water, they will just drift until they wash up onto a beach. After doing so, they stick to whatever is handy (rocks, shells, sand) and begin to grow. the smaller bud begin to fill with hydrogen, and as it grows, new buds form, and then float off. After about a week of doing this, the plant flies away yet again.
It will continue to fill with gas and float higher and higher, until eventually the pressure is to much for it, and it pops. Then, the spores that have been contained inside of it for so long will fall to the ground, (hopefully) starting the process over again.
The stickyglobes are everywhere, and they are so plentiful, they have even made their cousins, the stickyballs, go extinct on the beaches.
