Below is an illustration — a 'collage' panorama — I did in Photoshop of the "Spy Team Headquarters".
Navigation: You may need to download the images to see them whole, as previews may be truncated, depending on your screen resolution / browser zoom setting. Although, if you click on an image, it should zoom you in, and then you can click-drag on the middle mouse button to pan around.
The only sketch I did, before giving up on that strategy and figuring things out in Photoshop instead:
Here is a cropped view of the Spy Team HQ, only:
And here is the entire panorama ( 28Kx2400 ):
Spy Team HQ is located on
Playmobil Island ( a paracosm I developed
with — and largely
for 
— my 9 year-old nephew / no relation to the Playmobil Movie ), due east from the previously mentioned
Future Valley ( see "Space Patrol HQ" thread ). The panaroma is a north-to-south slice of the island.
To the south of Spy Team HQ lies
Serenity Valley, which is bisected by a wide river called "The Tomorrow River", flowing westward across the entire width of
Playmobil Island, toward the 'future' — except once a month during the full moon, from midnight to 4:00AM, when the river inexplicably reverses its course and flows 'upstream' ( east ), all the way to
Jurassic Valley, aka.
Playmo B.C.: not a good place to find yourself in the middle of the night, should you take a full ride on the river at that time!
Spy Team has a very efficient, secret ( naturally ), bullet-train underground network, allowing them to get in the vicinity of any theme / location on the island within minutes. They also have secret access tunnels to all the known jails, everywhere ( including Space Patrol's, who are frenemies — they are in good terms, at present — ), should one of their guys get captured.
Spy Team employs trained wolves, dolphins, whales, penguins, squirrels, owls and seagulls, for various tasks. Wolves are usually used for security ( ‘Wolf Patrol’ takes turns guarding the railway tunnels ), and for scaring people away from sensitive spots — though they also use animatronic monsters ( ex: Yeti ) for that purpose, from time to time!
Spy Team has a special arrangement with
Captain Blackheart, whose pirate ship is anchored in the big sea cave, to the south: "Don't try to break into our base, and we won't confiscate your ship — and your treasure ( we know where it is )!" A deal which Captain Blackheart, ever endowed with a keen sense of self-interest ( and self-preservation ), promptly accepted! Spy Team does keep an eye on them, along with all the known bad guys in the area, of course: Dr. Devil, Megalomax, Dr. Drone, Team SHARK, Ice Pirates, and Arctic Rebels — though none of these guys know where the Spy Team HQ is located.
Notes:
- This panorama took me over a month to complete, during the coronavirus confinement, and was mostly finished prior to starting the Space Patrol HQ ( which explains why it is not quite as polished as the latter ).
- RMDO refers to my nephew.
- The source *.PSB ( a large image format Photoshop required me to use ) is about 44Kx4K, and was designed to be printed on 9 borderless 8.5"x11" @ 300PPI
- If this panorama was built irl — klicky-scale, 1:24 —, it would be 73' long ( 22m ); I would personally love to see something similar at the Funpark in Zirndorf!
- Fun feature: the panorama can be made to wrap-around.
- This type of illustration is known in German as a 'Wimmelbild', and are typically found in children-oriented books called Wimmelbilderbuch ( literally: "teeming pictures book" ).
