I had to spend a while looking it up, because all I remember were the amazing characters and the Gummi Bears boats


I remember that one time when we went, my parents got my little brother and I these ridiculously awful Rescue Rangers outfits that were mostly brown, but had blue and red accents that we incredibly ugly, but we thought they were the coolest things ever. We wore them to the park every day after we got them.
Hopefully someone else here is around my age and visited the park then, because I imagine that if you weren't this will be completely crazy and uninteresting.

Okay, there's even a video:
