Piranha Ultimate Upgrade Kit

I proudly present my new MASK Piranha Ultimate Upgrade Kit to coincide with MASK’s 35th birthday.

MASK M.A.S.K. Piranha Ultimate Upgrade Kit

Probably your very first or second addition to your MASK collection, Sly Rax’s fish-out-of-water bike and sidecar is an awesome and truely iconic little toy, but often suffered from a broken cowl on the bike and the stickers suffered massively due to – inevitably – it being taken into the bath, pond or aquarium!

What you get –

  • 20+ Custom drawn, professionally printed and pre-cut stickers for your Piranha to make it POP! Full coherent instructions on this page! 

This is a full, highly detailed complete redraw of the original Pirahna stickers plus a bunch of new ones. Mainly an update with great print quality, super bright colours and smooth lines, this is a great example of how a new set of decals can breath new life into an old toy. Brand new stickers include control panels for both bike and submarine, and a remote-fired magnetic winch to explain how the sub is pulled back out of the water to reconnect with its bike-mounted launch bay!

As with all my other kits, I’ve created placement instructions for the kit below. Have fun and thank you so much for buying my stickers and keeping MASK alive!

Please refresh this page to ensure you have the most up-to-date instructions!


I also (always) recommend tweezers for some of the tiny, fiddly stickers.

Also, take your time! This is a fun hobby project for serious MASK fans!

First, remove the tired 30-year old stickers off your Piranha and clean it up if you can. You can clean any residual goo off with Zippo lighter fuel.  If you decide to remove the stickers later, they won’t damage the toy.

Thanks for supporting my MASK art and contribution to the MASK community!

I welcome your feedback. If you think my instructions look like Lester wrote them, let me know and I’ll try and improve them.

Do you have suggestions for other kits I should make?

I’d love to know what you think of my MASK Piranha stickers! You can contact me by email, my Riverglade.guru facebook page, or a MASK facebook group here if you have any questions or feedback. Visit my youtube channel! NEW – Follow me on instagram!

PS If you’re from Hasbro you should really offer me a job doing this! 🙂
