Yellow Land

They're actually just R-Bots that are glitched to look like B-Bots, or B-Bots glitched to function like R-Bots.

Great, simple (once you figure it out), and fun level! The design demonstrates an intricate use of various block types. There were plenty of surprises along the way that made for an exciting experience. Thank you!

How can you add several B Bots on the same game? Did you hack the QR Code??? Or maybe is it possible with an older version of the game?

"What you do is you fill the entire floor with zappers and then you put down a block. Afterwards you place a yellow robot on the block you just placed. This will make the block darker even though the yellow robot doesn't show up, so now all you have to do is place down more yellow robots wherever you please! Afterwards just start the level (you should crash) then delete all the zappers and boom! Multiple yellow robots! I hope you find this helpful!"

@trids try the level!

@meko OMG ! That's an incredible Mekorama bug and crash !!! Difficult to know exactly where the invisible B has been placed (since I did it without the block, straight on the zappers) but that does the trick (which is not a really one to me... )
Now I can play the level
Thanks for the tip !

Ha ha! Red or Yellow, that's a great level indeed! Thanks!

@Ashish Patel You're not obliged to add a block. I've filled the entire world (16x16) with zapper and added B Bots. That's disturbing because they doesn't appear. Launch the game then Mekorama crashes ! Launch again Mekorama then the bots appears You can now remove the zappers the B Bbots will remain.

Note on Mekorama crashes : that remains really weird because I launched the zappers world with B Bots a second time after the first crash and now my entire mobile phone crashes (black screen and no control) with the zappers sound in loop ! I had to restart everything...
