Well...I definitely know a lot on this subject.

As I've said elsewhere, I've been going to the park since I was two-years-old (now 18).
Hastings and surrounding area-As mentioned before, there was a
shooting gallery. It was a little weird...
-
The Enchanted Laboratory was a show that took place in the castle. I actually participated twice. I'm not sure when the show began, but it was there at least from 1989 (since it's in the tour video my family owns) to when Hastings was replaced with Ireland. The cast members would select two kids waiting for the show to participate and help out the main character (Northrup). First time I participated I believe I was 4 or 5, and the second was when I was 7.
Here is a picture of the certificates I received from participating:

-
Questor (freaking awesome) and
King Arthur's Challenge (sucked :/ )
-I know there were many shows in the theater before, but
Rockin' the Boat was very good while it lasted.

-
Threadneedle Faire. (The two games I really remember were a ladder game and whack-a-frog.)
-
Feathered Follies bird show.
-Nearby the gaming area there was a
tram station that would take visitors to the Brewery for a tour. I'm guessing it was removed due to an eventual lack of participation.
Festa Italia-
The Sea Dragon. I used to ride this thing all the time when I was little. It was great.

-Also mentioned before, there were
remote-control boats.
Oktoberfest/Germany Area-
Grimm's Hollow. Much smaller than Land of the Dragons of course, but fun while it lasted. I remember playing in sand near the gingerbread (?) house.
-
Red Baron. Worth a mention since it was moved to make room for DarKastle.
-
Drachen Fire. My FAVORITE coaster. I miss it...
-Some
thrill ride that reminds me of a spider. It was located near the swings and Der Katapult. My mom says it was an alright ride, but it was likely removed because it took forever to get people on and off the ride. I have no idea what the real name of it was. This ride is also in the tour video I own.
-
Random fact: BG held a competition to help design the main treehouse for the Land of the Dragons when I was in kindergarten. My drawing was one of many that was selected and once the play area was complete the winners got to go into the park before the park officially opened and play in it.
New France-
Eagle's Nest play area beneath part of the Log Flume. The only thing I can remember here is a big sort of air cushion everyone would jump on. There were also a lot of totem poles everywhere...
England-
Petting zoo.
-
Haunts of the Olde Country in the Globe Theatre. Involved a little boy ticking off a witch and meeting ghosts, and turning into a dog. Fun times.

-And evidently a looooooong time ago there used to be an
ice skating show inside the Globe Theatre. I never saw it of course, but it's in the 1989 tour video BG released.
-I also think I remember something involving the
Muppets in the Globe Theatre...but I can't remember what on Earth that would have been. (I'm possibly thinking of that 4D Muppets show in MGM Studios, but since the theaters have a different layout I think I might be right? I definitely remember the upper floor being used for something else besides the cannons in Pirates!4D.)
-There was also a
street show that would play outside the Globe Theatre involving a small band.
Park Itself-
BG used to have a dragon mascot.

I can't remember the dragon's name for the life of me, but it was in my older brother's colouring book from the park, which I think was from the mid-1980s. (One of the dragon's friends was a knight.

) The green dragon mascot also appears in the tour video I keep mentioning.
-On the way out of the park on some days, crew members would be passing out samples of Owl (??? There was an owl on the package, I don't remember what the actual name is) brand potato chips or pretzels. This was done until I was about 8 year old or so (I think).
And to end my post, here are old pictures that my mom took back when I was about 3. (...Yes...I am the little girl in front of the fence. lol.)
