Jelly Bloom is open for November, free all month. From November 14, seven animals are tangled in lost nets on the ocean map for the Net Rescue hunt. More new oceans are on the way.

Five math levels, from first counting at ages 2 to 4 up through times tables at 8 and over. Two oceans are free in full, and seasonal oceans like Jelly Bloom are free while they're open. The rest are one-time unlocks, never a subscription.
