Early G1's version of Ponyville called Ponyland, though I've re-imagined it with a special entrance gate. The card's info says:
HOFS-EN031:
Ponyland
Field Spell
This card's name is treated as "Ponyville" while face-up on the field. Once per turn: You can Special Summon 1 Nostalgic Pony-Type monster from your hand. You must control a Nostalgic Pony-Type monster to activate and to resolve this effect.
