Rare Thumpies

Rare Thumpies are very similar to their Common counterparts, being composed of a pair of sentient furballs with bouncy mushroom-like drums. However, the members of the pair are light green and light brown as opposed to pink and brown. Their looks are also odder than normal, with the green creature bearing yellow, zombie-like eyes without pupils, and worms coming out from inside its body. The brown creature is very similar to a ball of amassed rubber bands, and have pencils piercing through their bodies. Wisps of blue fur can be seen poking out from it. They have a butterfly on their stump.
