You can use texture stamps to make bumps and details as well as press in one end of various sized metal tubes to 'cut' in the circles. Then rub over those with an alcohol solution to soften.
Use Rubbing Alcohol on oil-based clays and water on water-based. Be careful not to brush on too much at one time, otherwise you'll turn it into one sludgey mess and destroy any texture you've got going.
For much larger bumps, these can be cut in with wire loop tools for sculpting. If you don't have any of these, they can be easily made but are cheap enough to buy.

I don't see how you could really get a believeable bumpy skin texture with a sponge alone. A toothpick would leave holes/dots.
You could maybe use a small fine sponge to soften details created by other tools as mentioned in my post above. Try making patches of details on lumps of clay, then molding them to make a texture stamp. You could make these of all shapes and sizes to suit different areas of your Trike sculpt.

I've never used it, I prefer oil-based clays as they can be re-used and do not dry out. Here's the clay you described:
Not sure if it's the best choice of clay for sculpting creatures with a lot of fine details as you'd be very limited time-wise before it dries and becomes non-workable. Maybe an oil-based clay such as Roma would have been a better choice. I would however be interested to know how you get on with this stuff.
