Here are some cheats and tips for the game Rugrats: Royal Ransom.
Stormin’ The Castle: Secret area:
When you get to the fourth area when you finish Angelica, there is a secret
key near the cabins in the front. When you go to the front, you will see the
key. Damage the bars to get the key, then go to the back of the arena. Look up
to find the gate with the keyhole. Get up there and go to the gate. Go inside
to find a lot of Reptar Funny Money.
