We found that colossal variations of resistance in 
La
0.225
Pr
0.40
Ca

Mn

 in about 
100
μ
s
 occur simultaneously with magnetic avalanches that last about 
1
ms
. These findings are interpreted as macroscopic fingerprints of the percolative phase separation upon application of the external magnetic field. Depending on the fraction of the ferromagnetic phase 
x
, the colossal magnetoresistance jumps appear to be caused either by fluctuations of 
x
, accompanied by fast propagation of the magnetic avalanches through the sample, or by a phase transition from charge ordered antiferromagnetic phase to charge delocalized ferromagnetic phase.
