A Rainbow frog is real and known as the Malagasy rainbow frog.
The Malagasy rainbow frog is a small, roundish, brightly colored species of frog with a distinctive white, orange–red, green and black pattern on the back, each area of which is clearly delineated.
The skin on the back of the rainbow frog is very smooth, but that of the grey belly is a little bit rough.
The Malagasy rainbow frog is an explosive breeder (meaning that the breeding season is short and begins suddenly) that breeds in groups in November–December just after the first heavy rainfall in the early rainy season.
A group often consists of a few tens of individuals and usually more males than females.
The Malagasy rainbow frog is endemic to the central part of southern Madagascar and occurs in the Isalo Massif.
It is present in the Isalo National Park where it is found in narrow canyons where the conditions are cool and humid.
Rainbow frogs are surprisingly well adapted to burrowing as well as rock climbing.
Being able to climb allows the species to escape flash floods.
To do this frog is equipped with wide, adhesive discs on the fore feet for clinging to vertical canyon walls.
Scaphiophryne gottlebei, commonly known as the Malagasy rainbow frog, ornate hopper, rainbow burrowing frog, red rain frog or Gottlebe's narrow-mouthed frog, is one of the most highly decorated frogs from Madagascar.
