Yellow-bellied Toad Bombina variegata

The Yellow-bellied Toad is native to central and southern Europe. It has a warty but plain, camouflaged top but, like other members of its "fire-bellied" family, has bright orange or yellow patches with blue or black on the underside (which can include limbs).

It shows its bright yellow/black (or orange/black) underside to potential predators to warn that it is poisonous. Its body is rounder and underside lighter than its close relative, the European Fire-bellied Toad whose range is mostly further east.
