I can't find any Gelatins in the Battle Coliseum. How do they appear and when?

Right now they've been defeated, the next wave was taken down because of a coding error with the achievements. They should be back up soon!

Thanks Virus.

sometimes additional waves are announced in the news, and sometimes you have to go and look as they've been added by stealth. It's typical for the un-announced waves to be more of the same kinds of gelatin-challengers that have been kindly added for peoples in other parts of the world/with busy schedules, while the announced ones include a stronger opponent.

Oh I didn't know.Thanks Solsticesprite

you are welcome. It hasn't been unusual in the past for the battle counters for marauding Gelatins to go awry. They get fixed eventually. It's too bad for now for people still working on Achievements for fighting them off. Gelatin attacks are seasonal and typical of later in the summer than this current wave, all September-ish, so they may yet have time to bring them into play again this year. One year (three years ago?) we had a spring attack also.

The new challenger is fun if you can take him.
