do we know when they were born? cause for monkey babies they seem pretty young looking. If they were born after the changes were made the telepathic enhancements would probably be passed down from mothers, chemicals would be by weaning as well though so ....strength maybe v

Since they're young and growing, it's probably possible that they did actually have the kobra venom injections, but because of the youth they'd get a smaller dosage, their bodies were more able to adapt to the changes and heal any baby-scars relatively quickly. kinda like how baby heads can be alll squished with no ill effects cause it just reforms.
