Easiest way (be aware, I did say it's the easiest, didn't say faststest 😅😅) to farm literally everything animal based, including cementing past), plus pretty good loot, like arrows, metal hatchet and so on

1rst step tame two

2nd go on the southern cave

-Set them to agressive

-After each room, check levels & hp points

-Empty their inventory, to get the loots from everything they'd kill

-ride the one with highest xp

3rd Once they're both with 1000xp, go breed them

4 start over to step 2, with three frogs

Once every one's got 3000xp, breed them again, and kill one of the parents

-Restart over and over, as the breeds would get 4000xp each

At some point (when you'd see that their hp doesn't go below 10-20%, for ex.)

Do the same steps, all over, with the 3 frogs, at the next cave, to get more xp, and better loots (not the lava one, unless you'd kee the ones you're not riding at the entrance, obviously)

Then, finally, once you got the gas mask, or whatever to breath from the swamp cave, process same way at this one

Obviously, you cane replace any cave with the swamps, or even the herbivores/carnivorous islands

Again, I did say it's the easiest way, not the fastest

Because once the frogs would be well imprinted enough, they would be able to take on their own the toughest creatures, and you'd just have to check their inventory, from time to time

The beelzebufo is useless at least in my pov

If you know you are in need of cementing paste.

Don't even bother taming this.

Because bugs are rare than scorpion or araneo

At least you know where to find those two unlike the bugs because you can't get cementing paste from scorpion or araneo

What you need to do is tame 2 dire wolves from the strong cave and make sure you level up their weight and melee then go to the swamp cave and run it

Direwolves gather chitin than beelzebufo use the chitin to make cementing paste

Megatherium would be better if it can enter caves but it can't

I think I might be the first person who was crazy enough to try this, but I discovered these frogs are actually pretty good for exploring the OCEAN. Here me out. The frogs hp is pretty low and his carry weight is also low, but the frog can swim fast enough to avoid threats, can breath underwater, and can surface fast enough to keep you from drowning. Obviously the frog cant fight megs or help you harvest resources underwater, but they make quick and efficient travel and can move seamlessly from land and aquatic environments. Obviously the ichyosaurus and diplocalus were designed for ocean exploration, but the beezle bufo works surprisingly well as an early ocean explorer.
