I'm looking through the soda available, and I find it fairly limited. Here are some ideas for additional soda off the top of my head:

• Mango Soda
• Melon Soda
• Peach Soda

This would take a little more effort, but possibly flavor mixing:

• Cherry Cola/Rootbeer/Lemon-lime
• Blackberry Rootbeer (seriously, this tastes amazing irl)
• etc.

Thank you for the ideas but I only add new food items/etc via Patreon or Comissions.
