Crumble Rumble 1, Retro Rampage 1 & Rolling Star Sola Collectible Locations

Among the many levels that Astro Bot has to explore, each of these cosmos has some features implemented as bonuses to rescue several stranded bots. In this case, Gorilla Nebula has three bonus levels: Retro Rampage 1, Rolling Star Sola, and Crumble Rumble 1.

Before entering any level, you can unlock these three levels by fully exploring Gorilla Nebula with DualSense and Astro. When you interact with certain elements, they will appear. This is a guide on how to rescue the three bots found in these three levels.

Bot 1 (Toro Inoue Bot)

There is only one bot to rescue in this special level named Rolling Star Sola, which depends on how you access the Gorilla Nebula group of levels. Near the end of the level, locate this bot and use a soccer armadillo to hit a flying UFO that is holding the Toro Inoue bot captive.

This character first appeared in the 1999 game Doko Demo Issyo, another excellent reference to the PlayStation world in these Astro Bot levels.

Bot 1 (Ryu Bot)

Retro Rampage 1, a short stage in another secret level, is only accessible by navigating through the Gorilla Nebula with the DualSense. You just need to quickly defeat some enemies to unlock the only bot available here.

The bot in question is Ryu from Street Fighter, one of the most iconic franchises in gaming history. This level will have a pixel art style that is truly amazing to admire in Astro Bot.

Bot 1 (MLB The Show Bot)

To wrap up this guide, the final secret level is Crumble Rumble 1, also accessed by exploring the Gorilla Nebula until a meteorite appears with this secret level. In this secret level, there is only one bot to unlock by completing a quick level with a few enemies.

The MLB The Show bot will appear, ready for rescue. Once you jump over a crumbling platform with three enemies, you can jump again and rescue the last bot.
