frog/axolotl DNA infuser ideas

[snoy]

I've been wanting to make frogs and axolotls usable with the new DNA infuser thingy, but I still need some more ideas for it. Here's what I have so far:
Frog tongue: Can be used to grab stuff from afar.
Frog lungs: Gives you a tackle. Changes your tackles to use little (or no) stamina but stops you from tackling into things or people. This lets you use the tackle to hop and leap around the place. Also makes you croak and ribbit every now and then.
Frog set bonus: Makes your skin green and slightly vulnerable to getting touched. Climb and stick to walls if you're not wearing shoes and gloves maybe?
Axolotl heart: Can slowly regenerate lost limbs and organs. Slower blood regeneration due to smaller size.

Both are good swimmers and like water but I can't think of much you can do with that ingame. Any more ideas?

amphibian skin should make you more vulnerable to dermally applied chemicals via splashing/patches

[Jacquerel]

you should need to get wet occasionally or start taking damage
while you’re safe from dehydration you should intermittently make floors wet when crossing them

Stepping on someone with the frug infused dna should make the funny frog noise.
